3. TECHNICAL BRIEF
3.10 LCD Interface
Figure 3.10.1. LCD Interface
The LM220CN1A module is a Color Active Matrix Liquid Crystal Display with an Light Emission diode(LED)
Back Light system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally White mode. This TFT-LCD has a 2.2 inch
diagonally measured active display area with 176 * RGB * 220 resolution. Each pixel is divided into R,G,B dots
which are arranged in vertical stripes. Gray scale or the brightness of the dots color is determined with a 6 bit
gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors.
FEATURES
- Display mode: Transmissive TN mode 262K colors
- LCD Driver IC: ILI9225B (1 chip for Gate & Source Driver )
- Interface : 8bit, 16bit CPU interface
- Backlight: 3 White LED(1 way)
- Standby, Still, Moving mode display
- Low power consumption driving
- Mobile Phone Application
