Product Profile
The EL640.480-A SB series displays are VGA compatible high-resolution electroluminescent (TFEL) flat panel displays. They replace the bulky CRT in control and instrument product designs. They feature an integrated DC/DC converter, and their compact dimensions save space that can allow addition of features or reduction in overall size. The displays are mechanically identical.
The display format of EL640.480-A SB series displays is VGA compatible (640 columns by 480 rows) with sixteen true shades of gray. The display supports and automatically detects all standard VGA modes.
The displays require a single +12Vdc power source and five basic types of input signals to operate :
1. Video Data or pixel information
2. Video Clock, pixel clock, or dot clock
3. Horizontal Sync
4. Vertical Sync
5. Blanking
EL Technology
The display consists of an electroluminescent glass panel and a mounted circuit board with addressing electronics.
Figure 1. EL Technology.
The EL glass panel is a solid-state device with a thin film luminescent layer sandwiched between transparent dielectric layers and a matrix of row and column electrodes. The row electrodes, in back, are aluminium; the column electrodes, in front, are transparent. The entire thin film device is deposited on a single glass substrate. The glass panel is mounted with an elastic spacer to an assembly support carrying the electronic circuit assembly board (ECA) mounted on the support. The driver electronics is connected to the EL glass panel with soldered lead frame interconnects. The result is a flat, compact, reliable and rugged display device.

The EL640.480-AD4 SB display includes a dark ICE (Integrated Contrast Enhancement) background in the display glass. ICE background significantly improves the luminance contrast of the display in bright ambients. ICE also removes the halo around the lit pixels in dark ambient making the appearance of each pixel crisp and clear.
The 640 column electrodes and 480 row electrodes are arranged in an X-Y formation with the intersecting areas performing as pixels. Voltage is applied to both the correct row electrode and the correct column electrode to cause a lit pixel. Operating voltages required are provided by an integrated DC/DC converter.

Programmable Features
Two data parallel input mode is selected when bridge DCON on the ECA is open (see fig. 2). In default configuration the DCON bridge is set. See page 9 for more details.
The method of gray scale coding can be selected either with COLMAP control input (J1/27) (see Signal Inputs on page 5) or with solderable bridge MAP on the ECA (see fig. 2). If COLMAP is left disconnected, MAP brigde defines the mode. If MAP is left open (default), colour mapping is selected. If MAP is bridged, binary coding is the method. Note that if COLMAP control input is used MAP has to be open. See page 8 for more details on colour mapping.
Notice: Only binary coding of input data can be used with Two Data Parallel mode. See Gray Shades and Two Data Parallel Mode in page 9.
For compatibility to previous versions of A series displays the horizontal and vertical positioning of the image can be adjusted with solderable bridges on the ECA of the display. VERPOS0–VERPOS2 (MSB) are for vertical positioning and HORPOS0–HORPOS3 (MSB) are for horizontal positioning (see Fig. 2). Both settings form a binary number where a set bridge is a "0" and open bridge a "1". The adjustment range for VERPOS is 0 to 7 upwards (default 000 for no shift) and HORPOS 7 right (0000) to 8 left (1111) (default 0111 for no shift).
Notice: Due to the fact that picture positioning is not supported by Planar multi-colour VGA displays and may not be supported by some future Planar VGA displays, the use of this feature should be avoided.

Display Features
The EL640.480-A SB series displays are timing and pin compatible with the feature connector on VGA display controller cards. Pins 1–26 on the feature connector connect directly to corresponding pins on data input connector J1 of the display. Pins 27–34 may be left disconnected.
Video Data
Gray Shades
Input signals D0, D1, D2, D3 (and D4, D5, D6, D7 in two data parallel mode) contain the four bit serial video data to be displayed on the screen. Pixel information is supplied from left to right and from top to bottom. The four data bits can be interpreted as colour data or binary gray shade codes.
The display is capable of displaying sixteen true levels of luminance. The four bit video input data can either be mapped to colour coding or binary gray shade coding. Colour coding is selected by pulling COLMAP control input HIGH. A LOW state in COLMAP control input selects binary coding. See 'Programmable Features' in page3 for setting the coding if COLMAP input is left disconnected.
Table 5. 16 levels of gray when colour mapping is used.
D3 D2 D1 D0 Colour Gray Level
0 0 0 0 Black 0 0 0 0 1 Blue 1 0 0 1 0 Green 5 0 0 1 1 Cyan 8 0 1 0 0 Red 2 0 1 0 1 Magenta 3 0 1 1 0 Brown 6 0 1 1 1 White 11 1 0 0 0 Gray 4 1 0 0 1 Lt. Blue 7 1 0 1 0 Lt. Green 12 1 0 1 1 Lt. Cyan 13 1 1 0 0 Lt. Red 9 1 1 0 1 Lt. Magenta 10 1 1 1 0 Yellow 14 1 1 1 1 White(High Int) 15
For maximum text readability, the default text brightness level is mapped in text modes 2+, 3+, 7 and 7+ to high intensity white (level 15). If colour coding is selected levels 11 and 15 are changed. If binary coding is selected, levels 7 and 15 are changed respectively. Please find complete description of VGA modes in page 11.

Self Test
Display Enable
The operation of the display can be tested using the SELFTST control input (J1/26). Self test is performed if SELFTST is HIGH or left disconnected. By applying power to the display without any other input, the display starts scanning, displaying all pixels with full brightness except a pattern of unlit pixels in the center of the topmost row.
The operation of the display can be shut off for screen save or minimal power consumption by a LOW state on ENABLE control input (J1/28). When disabled power consumption of the display drops to appr. 2 W. In normal operation ENABLE input should be pulled HIGH or left disconnected (internal pull-up)
Brightness Control
The brightness of the display can be adjusted from below 20% up to full brightness by a 50kΩ external logarithmic potentiometer between LUMPOT1
and LUMPOT2 control inputs (J3/1 and /2 respectively). The control function is achieved by sinking a small (<0.5 mA typ.) current from LUMPOT1 to LUMPOT2 (When open, the voltages are at 5 V and 0 V respectively).
If the two inputs are left disconnected, the brightness is at its maximum level.
Low Power Mode
The Low Power function reduces power consumption of the display to typically 11 W. The function reduces slightly the contrast and average brightness of the display. The function is selected by LOW state in _LOWPOW control input (J1/30). If the input is pulled HIGH or left disconnected, normal operation is selected.
Two Data Parallel Mode
For compatibility with flat panel controllers, it is possible to input the data of two pixels simultaneously by using the secondary data input lines D4–D7. This mode is selected when solderable bridge DCON is open. In default configuration bridge DCON is set.
Notice: Only binary coding of input data can be used with Two Data Parallel mode. See Gray Shades.
EMC
The conductive metal assembly support between the display glass and the electronics as well as the metal back cover act as a ground plane for EMI signals. In conjunction with data input connector J1, there is a connection lug from assembly support through the ECA. This lug can be used to ground the shield of the signal input cable. Note that the assembly support is also connected to the signal ground of the display (GND in J1).
For best EMC performance, the four display mounting ears should be tied to customer chassis ground. Care should be taken to avoid loops in system grounding.

The EMC of the end product can be additionally improved using the four layer board version of the display. One of the additional layers of this version is dedicated to signal ground. It provides an efficient ground path for high frequency interferences present in the system. See Ordering Information on page 23.
For more details on improving the EMC of the end product please contact Planar.
Display Operation Modes
The display supports all standard VGA display modes. It also supports the NORMAL mode which is similar to that used by most other Planar products. Mode selection is automatically performed by the display detecting the state of _BLANK at rising edge of VS and the polarities of the VS and HS input signals at the rising edge of the _BLANK signal. See timing diagrams on pages 12-14 for more details.
VGA Modes: In VGA modes _BLANK signal is used to frame the valid video data. The number of active pixels in each VGA mode is determined by calculating the number of VCLK pulses during the HS LOW time (T8 on timing diagrams). The 320 column modes are detected additionally by the amount of VCLK pulses during the front porch (T7 on VGA mode timing diagrams). In 320 and 360 column VGA modes each pixel data is displayed in two successive pixels.
In 720 and 360 column VGA text modes the data of every ninth pixel is omitted to be able to display the whole data line with 640 pixels. There is no data loss due to blank data in the ninth column of the text box.
The border timing included in _BLANK is taken into account in the interpretation of this signal and the video data during vertical borders is displayed in 350 and 400 line modes but ignored in 480 line modes. See details on setup and hold timing on page 15 and the timing of different VGA modes on page 12-13.
Normal Mode: In this mode only seven input signals are needed: video data (D0, D1, D2 and D3), video clock (VCLK), horizontal sync (HS) and vertical sync (VS). _BLANK is not used and should be pulled HIGH or left disconnected.
In Normal Mode the last 640 pixels before the fall of the HS are displayed. The topmost row displayed is the first HS HIGH time ending after HS Hold from VS time (T3 in Normal Mode page 14) from the rising edge of the VS. See details on setup and hold timing on page 15 and Normal Mode timing on page 14.
Timing Compatibility with Planar displays
The VGA mode detection of EL640.480-A SB series displays is compatible with Planar EL640.480-AM series displays and EL7768MS display and is downwards compatible with Planar EL640.400-C and -CB series displays (350 line and 400 line modes).

Installation and Handling
Mounting
Mounting of the EL640.480-A4 and -AD4 displays should be done using the four mounting ears of the metal assembly support. Note that all four mounting points are connected to the signal ground (GND in J1) through the assembly support.
Handling and Cleaning
Before handling the display, necessary precaution must be taken to prevent application of static charges to the display from the operator or tools.
The display is made of glass material and should be handled with proper care. Do not drop, bend or flex the display or allow hard objects to strike its surface.

Video Signal Input
For trouble-free data transfer from data transmitter to display input connector, a maximum cable length of 600 mm (24 in.) is recommended. In the case of VGA Feature Connector use, proper signal buffering should be ensured. In order to lower signal reflections, the connecting cable should be terminated with a matching series resistor at each of the eleven outputs of the signal source. Data input thresholds of the display are 74ACT CMOS compatible, and
data lines have 4.7 k pull up resistors and 100 series resistors connected at their inputs.
Avoiding Burn-in
As with any other light emitting display, luminance variation may be noticed if fixed patterns are displayed on the screen for extended periods. It is prudent to use a screen saver or image inversion to avoid burn-in.
Caution: Properly mounted, this display can withstand high shock loads as well as severe vibration in aggressive environments. However, the glass panel used in this display will break when subjected to bending stresses, high impact or excessive loads
To prevent injury in the event of glass breakage, a protective overlay should be used on the viewer side of the display.
Cleaning Caution: Clean the display glass with mild, water based detergants only. Apply the cleaner sparingly.
Warning: The product generates potentially dangerous voltages capable of causing personal injury (high voltage pulses up to 230Vac). Do not touch the display electronics during operation!
Automatic Overheat Protection: The display is provided with an overheating sensor to protect the display in the case of temporary overheating. When the temperature in the display rises over specified limits, the automatic circuitry limits the power consumption of the display and prevents the temperature to rise critical. When using a typical power consumption of 16W within the specified operating temperature range, the overheat protection is not needed.
Electrostatic Caution: The Planar display uses CMOS and power MOS-FET devices. These components are electrostatic sensitive. Unpack, assemble and examine this assembly in a static-controlled area only. When shipping use packing materials designed for protection of electrostatic-sensitive components.

Filter
The luminance contrast of the ICE version of the display EL640.480-AD4 is sufficient for operation without any contrast enhancement. For best overall performance in high or low ambient luminance levels, a neutral gray circular polarizing filter with anti-glare coating or etch is the usual choice. This filter will make the reflecting electrodes of the display darker and will improve the contrast ratio. The anti-glare coating on the filter should be facing the user. The ICE display -AD4 is as option available with a protectective film with an anti glare coating optically bonded directly on the display glass.
