您好，RGB屏幕的DB信号线有一个通用的标准，像RV1106使用的RGB666的标准就是6个引脚代表一个颜色分量，DB0到DB17的顺序是BGR，其他的CLK DE 和 SYNC 引脚查看RGB驱动的时序图就可以了解作用，相关硬件设计细节不做详细说明。LCD屏幕资料主要是屏幕尺寸和相关供电细节，这里仅放出屏幕的引脚说明，屏厂给的资料没有授权不能公开，感谢理解

您好，请帮忙确认一下，DB0 对应的 B 的最高位还是最低位？

Hello Crocodile
I also have the same question for custom board design.
Could you please help to review and confirm?
Thank you.

You can refer to the description of https://docs.espressif.com/projects/es ... _lcd.html , the main difference between the different models of RGB screens is that the initialization is different, and the data format during transmission is similar

Hello Crocodile
Thanks for your reference.
I checked and show mapping btw LCD connector on Luckfox Pico Ultra W to 40 pin LCD as the below:

Could you please help to review and confirm?
Thank you.

I am sorry, but i can only provide suggestions regarding third-party hardware designs or adapters. We are not in a position to take responsibility for the results, and therefore we cannot offer review or confirmation. Please make your own judgment. Thank you for your understanding.

Hello Crocodile
Yes, I understand this.
I used Luckfox Pico Ultra W dev board for customer product, so i hope that i can get the supporting from you( Luckfox engineer)
So, for the final could you please help to confirm about RGB bit order on LCD connector LuckFox Pico Ultra W?
DB0-DB17 on H2 connector on Luckfox Pico Ultra W will mapping with B[0:5]-G[0:5]-R[0:5] or B[5:0]-G[5:0]-R[5:0].
Thank you.

Referring to this image, your speculation should be correct

Hello Crocodile
Thank you for your feedback.
Yes, I see.
Really in your ESP32 reference link, it have a sample schematic to show option for both RGB888 and RGB666.
I will update the testing when making a new daughter board for Luckfox Pico Ultra W.
Thank you.
