4. FUNCTIONAL DESCRIPTION
4.1 External Interface (RGB Interface)
If one line data is latched, data latch register data is transferred to the source driver amp and then the display is outputted.

4.6 LCD Display Circuit
generate drive waveform outputs. The RL pin can change the shift direction of 528-bit data by selecting an appropriate
direction for the device-mounted configuration.
The
RGB display data of one line (S0 to S527) are latched to the data latch register through parallel data bus (PD) in orderly.
The display data (PD17-PD0) are written according to the control of the data enable signal (ENABLE) in synchronization
Refer to 6. EXTERNAL DISPLAY INTERFACE.
The
This system interface transfers the data to the internal control register for power control, display control, gamma
The gray-scale voltage generator generates LCD driver voltages which correspond to the gray-scale levels as specified
The display timing generator generates the interface signals such source output, common output and gate driver from
The built-in power supply circuit generates (powers of) VCIX2, VLCD63, VGH, VGL and VCOM voltages that are
The LCD display circuit consists of 528 source drivers (S0 to S527).
Display pattern data are latched when 528-bit data have arrived. The latched data then enable the source drivers to
