Method for realizing integration of display image processing and timing control chip

Abstract

The invention relates to a method for realizing integration of a display image processing and timing control chip, which comprises the following implementation steps: (1) according to a signal flow of a display system, an image processing chip and a timing control chip are arranged in one chip; at the back end of image processing, a low voltage differential signaling (LVDS) signal output from a display control link is directly input into a data latch of a timing control (TCON) module; after data processing, the LVDS signal is output from a Mini-LVDS transmitting module; a source pole and gate pole control signal generating link is embedded into the image processing chip; and the output of the chip is a Mini-LVDS signal and corresponding control signals which are directly received and used by a liquid crystal display (LCD) panel; (2) a circuit board is in an integration structure, and except a power supply circuit board, other function modules are all concentrated on the circuit board; and (3) a power supply interface and an external signal input interface are arranged at the lower end of the back part of a display; and after the integration design of the circuit board is adopted, the liquid crystal panel needs to be flipped up and down. The invention has simplified structure, simple process and reliable performance.

Description

technical field [0001] The invention relates to a method for realizing the integration of display control chips, in particular to a method for realizing the integration of display image processing and timing control chips. Background technique [0002] With the rapid upgrading of the electronic market, LCD products have become the mainstream of consumption, the demand is increasing, and the output is also increasing. Therefore, it is urgent to improve production efficiency and improve production processes. [0003] The display function system is also applicable to the display system including Scaler (image processing, or called Display Controller, display control) and TCON (Timing Controller, timing control) functions. [0004] The currently developed display driver circuit has separate Scaler modules and TCON modules. Among them, the Scaler module is placed on the main board (Main Board), which mainly realizes the processing of various input signals, OSD (On-Screen Display...

Problems solved by technology

In this design scheme, the Main Board and X-Board are separated and independent, and the two circuit boards need to be connected through a special LVDS signal line; in terms of manufacturing, two separate printed circuit boards need to be made, and the two circuit boards need It is fixed separately and needs to be connected with signal lines during assembly. The production process is cumbersome, and the circuit boards of the two parts have a large area and the utilization rate is not high, which often increases the production cost.
