LCD Module User Manual 2 Absolute Maximum Ratings Items Power Supply voltage Operating Temperature Storage Temperature Condition No Condensation No Condensation Note: *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, TOP=25℃ *3. Ambient temperature when the backlight is lit (reference value) *4. Any Stresses exceeding the Absolute Maximum Ratings may cause...

LCD Module User Manual Basic Operation Function Descriptions HMT104ATA-C TML files Picture files ICONS files UART interface Custom Memories Touch Panel VP variables Control and Draw Engine TML files, Picture files, ICON files are stored inside FLASH memory area. They are preloaded to HMT104ATA-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....

LCD Module User Manual 5 Optical Characteristics Item View Angles Contrast Ratio Response Time TOFF White Blue Uniformity NTSC Luminance 1.IF= 40 mA, and the ambient temperature is 25℃. 2. The test systems refer to Note 1 and Note 2.

LCD Module User Manual Note 1: The data are measured after LEDs are turned on for 5 minutes. LCM displays full white. The brightness is the average value of 9 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°)): Luminance When LCD is at “White” state Contrast = Ratio(CR) Luminance When LCD is at “Black” state (Contrast Ratio is measured in optimum common electrode...
