Video frequency driving system and its method for organic light emitting diode display screen

Abstract

This invention relates to a video drive system for the display screen of an organic LED including a single-chip processor control module, an outer data storage module, an organic LED display screen control module and a supply module characterizing in also including an image data decode module for converting difference image signals to R,G, B signals and field and line synchronous signals and image signals of the drive system input end pass through the DVI interface module to connect with said decode module, a FPGA process module for processing said signals of said RGB signals and the synchronous signals to the RGB image data signals, in which, image data are transmitted to the decoder for process when passing through the DVI data line and the compressed data are processed in the FPGA process module then to transmit the processed image data to the OLED control module for analog transformation and finally the analog signals are input into the OLED display screen to be displayed continuously.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to an online driving technology of a video organic light emitting diode (OLED) of an organic electroluminescence display screen. Background technique [0002] At present, flat panel display devices are changing with each passing day. As a new member of flat panel display devices, the organic light-emitting diode display is still in the development stage in China, and the development of dynamic image driving circuits for this display device is also in its infancy in China. [0003] The existing organic light emitting diode dynamic display driving circuit and method can be briefly described as follows. The organic light-emitting diode dynamic display driving circuit includes a power supply module, a single-chip microcomputer control module, an external data storage module and an organic light-emitting diode display control module, and the organic light-emitting dio...

Problems solved by technology

[0004] The disadvantage of the prior art is that the memory for storing image data and programs is a Flash memory, which is limited by the internal ROM storage capacity of the memory, and the amount of image data stored is very limited, usually only the image data of a section of dynamic image can be stored. Therefore, existing The dynamic image driving circuit and method of the organic light emitting diode display can only drive the organic light emitting diode display to repeatedly display a segment of dynamic images or characters, but cannot support the dynamic display of online video image data
