A display control circuit and display device

Abstract

A display control circuit and a display apparatus, comprising: a timing controller (201) for transmitting a data signal and forming image information after processing the data signal; a frame buffer (101) for storing the image information and processing the image information and outputting same to the timing controller (201); a data drive circuit (202) for providing the data signal to a display device, and controlling a display image of the display device; and a power supply management integrated circuit (102) for managing the electric energy of the timing controller (201), the frame buffer (101) and the data drive circuit (202). The frame buffer (101) and the power supply management integrated circuit (102) are integrated on a first integrated circuit (10), and the timing controller (201) and the data drive circuit (202) are integrated on a second integrated circuit (20). The display control circuit and the display apparatus are low in production cost, and can be better adapted to the demands of high-definition resolution of a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display control circuit and a display device. Background technique [0002] The timing controller used in the display control circuit of the display device. The frame buffer is a necessary device. For example, the overdrive technology of the liquid crystal display needs to be applied to the so-called frame buffer (Frame Buffer) to store each frame. image information. The current frame buffer is integrated in the timing controller by the packaging program of the timing controller, that is, the other parts of the timing controller and the frame buffer are produced separately, and then packaged together by the packaging program. The packaging process Complicated and costly. Today, with the advent of the era of high-definition television, due to the increasing image resolution, many algorithm technologies that need to use frame buffers need to process huge amounts of data, so th...

The packaging process Complicated and costly

Today, with the advent of the era of high-definition resolution TVs, due to the increasing image resolution, many algorithm technologies that need to use frame buffers need to process huge amounts of data, so the cost of frame buffers has also increased significantly.

At the same time, since the timing controller, frame buffer, power management integrated circuit and some other functional circuits in the display control circuit of the display device are usually placed on the same circuit board, the circuit board is bulky and needs to be placed on the The location of the display device is specially set, so the volume of the display device becomes larger, bulky and costly
