*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,

and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃

*3. Ambient temperature when the backlight is lit (reference value)

*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.

Control and Draw Engine

- TML files, Picture files, ICON files are stored inside FLASH memory area.

They are preloaded to HMT080ATA-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 TML files

- VP variables memory is inside RAM area,

it provides real time access via UART by the HOST or display onto the TFT by TML file.

- 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

Note 1:

Note 2:

The data are measured after LEDs are turned on for 5 minutes.

The definition of viewing angle:

LCM displays full white. The brightness is the average value of 9 Refer to the graph below marked by θ and Ф

measured spots. Measurement equipment SR-3A (1°)

Measuring condition:

- Measuring surroundings: Dark room

- Measuring temperature: Ta=25 ℃ .

- Adjust operating voltage to get optimum contrast at

the center of the display.

Note 3:

The definition of contrast ratio (Test LCM using SR-3A (1°)):

Note 4:

Contrast

Luminance When LCD is at “White” state

Definition of Response time. (Test LCD using BM-7A(2°)):

Ratio(CR)

Luminance When LCD is at “Black” state

The output signals of photo detector are measured

(Contrast Ratio is measured in optimum common electrode

when the input signals are changed from

voltage)

“black” to “white”(falling time)

and from “white” to “black”(rising time), respectively.

The response time is defined as

the time interval between the 10% and 90% of amplitudes.Refer to

figure as below.

Note 5:

Note 6:

Definition of Color of CIE1931 Coordinate and NTSC Ratio.

The luminance uniformity is calculated by using following formula.

△ Bp = Bp (Min.) / Bp (Max.)×100 (%)

Color gamut:

Bp (Max.) = Maximum brightness in 9 measured spots

Area of RGB triangle

X100%

Bp (Min.) = Minimum brightness in 9 measured spots .

Area of NTSC triangle

Note 7:

Measured the luminance of white state at center point
