1. General Description

HD1051 is 10.4” Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Lamp (CCFL) backlight system. The matrix employs amorphous silicon Thin Film Transistor as the active element. It is a transmissive type display operating in the normally black mode. This TFT-LCD has a 10.4 inch diagonally measured active display area with XGA resolution (768 horizontal by 1024 vertical pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus presenting a palette of more than 262,144 colors.

The HD1051 is intended to support applications where high brightness is a critical factor. In combination with the vertical arrangement of the sub-pixels, the LF1051 characteristics provide an excellent flat panel display for office or industrial automation products or daylight applications. (LF1051=HD1051+LI2801)

3. Electrical Characteristics

The HD1051 requires three power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD. Third is for CCFL heater.

C. The values specified apply to all logic inputs; Hsync, Vsync,

Clock, data signals, etc.

3. The variance of the voltage is ± 10%.

4. The output voltage at the transformer in the inverter must be high considering to the loss of the ballast capacitor in the inverter.

5. Lamp frequency may produce interference with horizontal sync. frequency and may cause beat on the display. Therefore lamp frequency shall be detached as much as from the horizontal sync. and from the harmonics of horizontal synchronous to avoid interference.

6. The lamp power consumption shown above does not include loss of external inverter.

7. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial value at the typical lamp current.

*Due to the lamp specification only the approved inverters by Litemax LCD is recommended for this LCD module. (See the end of spec. for inverter spec.)

4. Power On/Off Sequences

To prevent a latch-up or DC operation of the LCD module, the power on/off sequence should be as shown below.

• 0 < T2 ≤ 50 ms

• 100 ms ≤ T3, T4

• 0 < T5 ≤ 50 ms

• 1 sec < T6

Note: 1. Please avoid floating state of interface signal at invalid period.

2. When the interface signal is invalid, be sure to pull down the power supply for LCD Vcc to 0 Vcd.

3. Lamp power must be turn on after power supply for LCD and interface signal is valid.

Notes 1. Contrast Ratio (CR) is defined mathematically as :

Surface Luminance with all white pixels

Contrast Ratio =

Surface Luminance with all black pixels

2. Surface luminance is the center point across the LCD surface 50cm from the surface with all pixels displaying white. For more information see Appendix B.

3. The uniformity in surface Luminance, δ 9, and then dividing the minimum L

WHITE is determined by measuring L

of 9 points luminance by maximum L

at each test position 1 through

ON

15. PRECAUTIONS

Please pay attention to the followings when you use this TFT/LCD module.

15.1 MOUNTING PRECAUTIONS

(1) You must mount a module using holes arranged in four corners.

(2) You should consider the mounting structure so that uneven force (ex. twisted stress) is not applied to the module. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. (3) Please attach the surface with a transparent protective plate in order to protect the polarizer LC cell. Transparent protective plate should have sufficient strength in order to resist external force. (4) You should adopt radiation structure to satisfy the temperature specification. (5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former generates corrosive gas of attacking the polarizer at high

temperature and the latter cause circuit break by electro-chemical reaction.

Page 18

(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead. And Please do not rub with dust clothes with chemical treatment. Do not touch the surface df polarizer for bare hand or greasy cloth. (Some cosmetics are detrimental to the polarizer.) (7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois soaked with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluen and alcohol because they cause chemical damage to the polarizer. (8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes deformations and color fading. (9) Do not open the case because inside circuits do not have sufficient strength.

15.2 OPERATING PRECAUTIONS

(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage : V = ± 200mV (Over and under shoot voltage). (2) Response time depends on the temperature. (In lower temperature, it becomes longer.) (3) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And in lower temperature, response time (required time that brightness is stable after turned on ) becomes longer. (4) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. (5) When fixed patterns are displayed for a long time, remnant image is likely to occur. (6) A module has high frequency circuit. It might be necessary to shield the electromagnetic noise in your integrating system. (7) When a Backlight unit is operating, it may make sounds. It might be necessary to shield your

integrating system to cut down the noise.

15.3 ELECTROSTATIC DISCHARGE CONTROL

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wristband etc . . And don’t touch I/F pin directly.

15.4 STORAGE

When storing modules for a long time, the following precautions should be followed.

(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 (2) The polarizer surface should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped.

o

C and 35 oC at normal humidity.

15.5 HANDLING PRECAUTIONS FOR PROTECTION FILM

(1) When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion- blown equipment or in such a condition, etc..

Page 19

(2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to remain on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer. (3) When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the polarizer after the protection film is peeled off. (4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal- hexane.
