A build-in power on reset circuit for VDD and VDDIO is provided within the integrated LCD
driver IC. The LCD module is in power save mode in default, and a standby releasing is
required after VDDIO power on through serial control. Please refer to the register STB setting
for detail.
Note 2: The power supply of digital interface, VDDIO, is for the 1.8V digital interface requirement in the
future. These digital signals are DCLK, HSYNC, VSYNC, D7~D0, CS, SDA and SCL. If the
digital interface level is 3.3V, please short the power pin VDD and VDDIO to 3.3V. In other
words, no matter the voltage level of VDDIO is 1.8V or 3.3V, the voltage level of VDD needs to
be kept 3.3V.

Note 1: Test Condition: 8colorbar+Grayscale pattern, UPS051 mode, DCLK=27MHz, Frame rate: 60Hz,
other registers are default setting.
Note 2: VGH and VGL are output voltages of integrated LCD driver IC.
Note 3: The brightness of LCD panel could be adjusted by the adjustment of the AC component of VCOM.
Note 4: VCDC could be adjusted, so as to minimize flicker and maximum contrast on each module.
