*4. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional

operation of this device at other conditions beyond those listed in the specification is not implied and prolonged

exposure to extreme conditions may affect device reliability.

-

Display UI files, Picture files, ICON files are stored inside FLASH memory area.

They are preloaded to HMT090ATA-C for stand alone interface use.

-

Those files are preloaded via USB interface as an USB drive.

-

All the interface flow and the touch response are based on the preloaded files

-

VP variables memory is inside RAM area, it provides real time access via UART by the HOST or

display onto the TFT.

-

Custom Memories are inside FLASH memory area

It can be accessed via UART interface by the HOST.

-

Control and Draw Engine executes HOST commands and response respectively

-

It also reports the real time Touch Key number to the HOST

6 Touch panel Design Precautions

1. It should prevent front case touching the touch

panel Active Area (A.A.) to prevent abnormal

touch.

It should left gab (e.g. 0.2~0.3mm) in between.

2. Outer case design should take care about the area outside the A.A.

Those areas contain circuit wires which is having different thickness. Touching those areas could de-

form the ITO film. As a result case the ITO cold be damaged and shorten its lifetime.

It is suggested to protect those areas with gasket (between the front case and the touch panel).

The suggested figures are B≥0.50mm; C≥0.50mm 。

3. The front case side wall should keep space

(e.g. 0.2 ~ 0.3mm) from the touch panel.

4. I In general design,

touch panel V.A. should be bigger than the LCD V.A.

and touch panel A.A. should be bigger than the LCD A.A.
