STRUCTURE AND FUNCTIONS A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are connected to the panel, the backlight assembly is attached to the backside of the panel. RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT cells. Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when activated by the data source. By regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity.

POWER SUPPLY DESIGN (1) 12 V for backlight should be started up within 80 ms, otherwise, the protection circuit makes the backlight turns off. (2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals become ineffective mode. To reset this mode, turn off the power once and turn on the power while UP and DOWN are connected to GND. Then, the mode will be released. (3) Inverter current wave Inverter current wave is as follows.
2700 (mA) typ 0 (mA) Duty Luminance control frequency
maximum luminance control: 100 % minimam luminance control: 20 % Luminance control frequency = Input Vsync frequency x K Input Vsync frequency 75 Hz: K = 4.6 Input Vsync frequency > 75 Hz: K = 3.6
(4) Ripple of supply voltage Please note that the ripple at the input connector of the module should be within the values shown in this table. It the ripple is beyond these values, the noise may appear on the screen.
VDD (for logic and LCD driver) Acceptable range 100 mVp-p VDDB (for backlight) 200 mVp-p

* These preset timings are not included in the specifications of the LCD module. Use preset timing only after careful evaluation. Note 1. Please bear in mind slight adjustment (multiplication value, clock delay, and display location) is required as a result of equipment variation even if input is performed with the display timing of this table. Readjustment, however, is unnecessary because adjusted values are stored in memory for every preset number. Display is controlled with preset timing near HS and Vsync frequency even if a signal with a timing other than the preset display timing is input.

2. The device may not function normally if a signal is input that differs from the timing shown in the above table by a large margin. In addition, the device will not operate normally if waveforms are distorted by rounding of Hsync or Vsync waveforms, noise, and others factors, even for a signal with the same timing as shown above. Example For 640 x 480 dots, HS: 37.861 kHz, and Vsync: 72.809 Hz, the image is displayed with preset number 6. Adjustment may not be synchronized if the expansion rate (scaling factor) or other values differ when the device is used with a display timing other than a preset one. Therefore, only use a non-preset display timing after careful evaluation. 3. Display colors may change during Sync on Green (SonG) input. 4. SonG signal types: (1) SonG type A An equivalent Hsync pulse is not present during Vsync period.

EXPANSION FUNCTION (REFERENCE) HOW TO USE EXPANSION MODES Expansion mode is a function to expand screen. For example, VGA signal has 640 x 480 pixels. But, if the display data can expanded to 2.0 times vertically and horizontally, VGA screen image can be displayed fully on the screen of SXGA resolution. This LCD module has the function that expands vertical direction as shown in Table 1. And expanding horizontal direction is possible by setting input CLK frequency equivalent to the magnification. It is necessary to make this CLK outside of this LCD module. Please adopt this mode after evaluating display quality, because the appearance in expansion mode is happened to be relatively bad in some cases. The followings show display magnifications for each mode.
Magnification Input display SXGA XGA SVGA VGA VGA text PC9801 MAC Number of pixels Vertical 1280 x 1024 1024 x 768 800 x 600 640 x 480 720 x 400 640 x 400 832 x 624 1.0 1.25 1.6 2.0 2.5 2.5 1.6 Horizontal 1.0 1.25 1.6 2.0 1.7 2.0 1.5
Note
Note The horizontal magnification multiples the input clock (CLK). Input CLK = system CLK x horizontal magnification Example: In case of SXGA and VGA, CLK frequency can be decided as follows. SXGA: System CLK (108.0 MHz) x 1.0 = 108.0 MHz VGA : System CLK (25.175 MHz) x 2.0 = 50.35 MHz
