4. Absolute Maximum Ratings

Operating Temperature

*1. This rating applies to all parts of the module. And should not be exceeded.

*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.

5. Electrical Characteristics

5.1 DC Characteristics

Input logic high voltage

Input logic low voltage

*1.Be sure to apply VCC and VGL to the LCD first, and then apply VGH.

*2: VCC setting should match the signals output voltage (refer to Note 3) of customer’s system board.

*3: DCLK,HS,VS,RESET,U/D, L/R,DE,R0~R7,G0~G7,B0~B7,MODE,DITHB.

5.2 Current Consumption

Vcc=3.3V,GND=0V,T a =25  C

Luminance uniformity

Note 1: Definition of optical measurement system.

The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical

properties are measured at the center point of the LCD screen. All input terminals LCD panel must

be ground when measuring the center area of the panel.

Note 4: Definition of Response time

The response time is defined as the LCD optical switching time interval between “White” state and

“Black” state. Rise time (T ON ) is the time between photo detector output intensity changed from

90% to 10%. And fall time (T OFF ) is the time between photo detector output intensity changed from

Note 5: Definition of color chromaticity (CIE1931)

Color coordinates measured at center point of LCD.

Note 6: Definition of Luminance Uniformity

Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at the

center of each measuring area.

Luminance Uniformity (U) = Lmin/ Lmax

L-------Active area length W----- Active area width

Lmax: The measured Maximum luminance of all measurement position.

Lmin: The measured Minimum luminance of all measurement position.

Note 7: Definition of Luminance:

Measure the luminance of white state at center point.
