Display device and image transmission method used by it

Abstract

A display device consists of driving module with color mixing module and display module. it is featured as using said driving module to receive image signal, outputting an image signal by driving module after received image signal is processed with color mixing module and using display module to receive image signal outputted by driving module.

Description

technical field [0001] The present invention relates to a device and a signal transmission method, and in particular to a display device and an image transmission method. Background technique [0002] At present, the transmission of general images is first passed through a driver module, and then processed in the driver module and then output to the display module. [0003] The drive module includes a central processing unit, and when an image signal is input, the received image signal is processed by the central processing unit and then an image signal is output. [0004] When the driving module outputs the image signal to the display module, it can use many ways. [0005] Among them such as figure 1 As shown, an image signal is input into the drive module 102, and the image signal obtained after signal processing by the drive module 102 is output to the display module 104 in units of 18 bits. Although this will speed up the transmission speed, it is relatively Many Gene...

[0006] And if the display panel used has a buffer (buffer), such as figure 2 As shown, an image signal is input into the drive module 202, and the image signal obtained after signal processing by the drive module 202 is output in units of 8 bits, in the form of a red (R) signal, a green (G) signal and a blue (B) signal. ) signals are separated and sent to the display module 204 with a buffer. Usually, the central processing unit supports this method, but many general-purpose input and output (GPIO) pins are still used.

[0007] In addition, there is another transmission method, such as image 3 As shown, the display panel in the figure also has a buffer. When an image signal is input to the driver module 302, the image signal obtained after the signal processing by the driver module 302 is output in units of 6 bits, and the red (R) signal , the green (G) signal and the blue (B) signal are separated and transmitted to the display module 302 with a buffer. Although this transmission method has improved the above-mentioned shortcomings, another problem has arisen because the previous 8 bits are 256 color output, but after changing to 6-bit, only 64-color output, so if there is no color you want, you can only choose a color with a similar color at most, so there may be a problem of data loss.
