Product ProfileProduct Profile

The EL4836HB and the EL4836HB-ICE displays are
low power, rugged, high-resolution electroluminescent
(TFEL) flat panel displays. They replace the LCD or bulky
CRT in instrument product designs. Their compact
dimensions save space that can allow addition of features
or reductions in overall size. They are designed to
function in extreme environments, and the crisp displays
are viewable under most lighting conditions at wide
viewing angles. Their ease of installation reduces system
integration costs.

The EL4836HB and the EL4836HB-ICE are 276
column by 128 row displays with a resolution of 48 dots
per inch. The pixel aspect ratio is 1:1. The LCD-type
interface is TTL-compatible and is designed for hardware
compatibility with the Hitachi HD61830B or equivalent
LCD controller. These displays may be driven at frame
rates up to 120 Hz for applications requiring extra
brightness.

The displays require +5V/+12VDC or +12VDC
only power and four basic signals to operate:

1. Video Data or pixel information (VID)

2. Video Clock, pixel clock, or dot clock (VCLK)

3. Horizontal Sync (HS)

4. Vertical Sync (VS)

Operations ManualOperations Manual

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 aluminum;
the column electrodes, in front, are transparent. The
entire thin film device is deposited on a single glass
substrate. A circuit board is connected to the back of the
glass substrate. Components are mounted on this circuit
board within the same area as the electroluminescent
viewing area on the glass panel. The circuit board is
connected to the glass with metal-on-elastomer
interconnect technology. The result is a flat, compact,
reliable and rugged display device.

The EL4836HB-ICE display includes a light absorbing
Integral Contrast Enhancement (ICETM) construction of
the display glass. ICETM background significantly improves
the luminance contrast of the display in bright ambients,
and makes the display easier to read by increasing the
crispness of the pixels.

The 276 column electrodes and 128 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

V(t)

the correct column electrode to cause a lit pixel.
Special operating voltages required are provided
by a DC/DC converter.

The DC/DC converter cannot be tested separately.
It requires an active low enable signal from the display
to activate the high voltage section. The display pro­vides this signal after detecting the presence of video
signals at its input.

The DC/DC converter has been properly calibrated
at the factory to the EL display by means of a voltage
output adjustment. The converter should not need
adjustment in the field. If the DC/DC converter and
display become separated the following procedure can
be used to set the converter to the proper voltage:

1. Ensure power to the DC/DC converter is off.

2. Turn trimpot R20 on the DC/DC converter fully

counterclockwise (ccw). Do not adjust R19.

3. Connect the DC/DC converter to the display

using the flat cable.

9. Adjust trimpot R20 on the DC/DC converter
clockwise (cw) until the voltage reading of the DVM
is equal to the V (ALL ON) voltage ±1V, as specified
on the display. Do NOT exceed 235V. Do NOT
