9.20 External Light Source

The operation of the module can meet customer’s Environmental reliability requirements.

9.21 Oscillator

The chip has on-chip oscillator that does not require external components. This oscillator output signal is used for system

clock generation for internal display operation.

9.22 System Clock Generator

The timing generator produces the various signals to driver the internal circuitty. Internal chip operation is not affected by

operations on the data bus.

9.23 Instruction Decoder and Register

The instruction decoder indentifies command words arriving at the interface and routes the following data bytes to their

destination. The command set can be found in “ Command” section.

9.24 Source Driver

The source driver block includes 240x3 source outputs (S1 to S720), which should be connected directly to the TFT-LCD.

The source output signals are generated in the data processing block after the data is read out of the RAM and latched,

which represent the simulatance selected rows.

9.25 Gate Driver

The gate driver block include 320 chanel gate output (G1 to G320) which should be connected directly to the TFT-LCD.
