4.4.2 DPI Interface pixel format

The Pixel clock (DCLK) runs all the time without stop. It is used to enter VS, HS, DE and D[17: 0] states

when there is a rising edge of the DCLK. The DCLK cannot be used as the internal clock for other functions of

Vertical synchronization (VS) is used to indicate when a new frame of the display is received. This is low

enable and its state is read to the display module by a rising edge of the DCLK signal.

Horizontal synchronization (HS) IS used to indicate when a new line of the frame is received. This is low

enable and its state is read to the display module by a rising edge of the DCLK signal.

Data Enable (DE) is used to indicate when the RGB information that should be transferred in the display is

received. This is a high enable, and its state is read to the display module by a rising edge of the DCLK signal.

D[17:0] is used to indicate what is the information of the image that is transferred on the display (when DE = 0

(low) and there is a rising edge of DCLK). D[17:0] can be 0(low) or 1(high). These lines are read by a rising

edge of the DCLK signal. In RGB interface modes, the input display data is written to GRAM first then outputs

the corresponding source voltage according to the gray data from GRAM.

LCD Module User Manual

IOVDD and VDD can be applied or powered down in any order. During the Power Off sequence ,if the LCD is

in the Sleep In mode, VDD and IOVDD must be powered down with a minimum of 120 msec.If the LCD is in

the Sleep In mode, VDD and IOVDD can be powered down with a minimum of 0msec after the /RST has

been released. /CS can be applied at any time or can be permanently grounded. /RST has priority over /CS.

1. There will be no damage to the ILI9488 if the power sequences are not met.

2. There will be no abnormal visible effects on the display panel during the Power On/Off Sequence.

3. There will be no abnormal visible effects on the display between the end of the Power On Sequence and before receiving the Sleep

Out command, and also between receiving the Sleep In command and the Power Off Sequence.

4. If the /RST line is not steadily held by the host during the Power On Sequence as defined in Sections 11.1 and 11.2 ( ILI9488

datasheet ), then it will be necessary to apply the Hardware /RST after the completion of the Host Power On Sequence to ensure

correct operations. Otherwise, all the functions are not guaranteed.

5. When the power is turned on, the climb period timing (Trise) must be greater than 10us.

6. Keep data pins D[17:0] at low level, or IOVDD comes later
