Imx6ul chip, LCD circuit hardware design RGB 2 bit down low, software configuration implementation R

Time:12-23

As title, imx6ull drive LCD, originally is 24 bit LCD, now 888 to 666 the line of hardware design, and then in the device tree configuration is also configured to 666 models, the result is the LCD driver, but the picture is very fuzzy, kneeling, every brother please help to analysis the reason,



The specific project according to the following several aspects elaborated

(1) hardware circuit

(2) the software code: configuration in the device tree and LCD manual

(3) the picture

a, hardware circuit design is as follows:

[R1 R2 R7], [G1 to G2 G7], [B1 B2 B7] together, their actual tests also tested manually cut line of low 2 bit RGB directly to GND,





2, configuration in the device tree below



3, the following picture, very fuzzy




Thank you kindly, help to analysis analysis, thanks!!
