Abstract

The invention discloses an LED display control chip. The display control chip comprises a logic control device, an LVDS communication module, a function memory, an image cache, a common pole control logic module and a display control module, wherein the logic control device is connected with the image cache, an LED detection module, the common pole control logic module, the display control module,the function memory, a low-voltage differential signaling (LVDS) communication module and a low dropout regulator (LDO); the LVDS communication module is used for transmitting image information or signal commands to the logic control device; the function memory is used for correcting and configuring signal commands written in by the logic control device; the image cache is used for storing imageinformation; the common pole control logic module is used for receiving first control commands of the logic control device and carrying out operations of turning on or off common poles of target LED devices; the display control module is used for receiving second control commands of the logic control device and carrying out operations of turning on or off R / G / B primary color grades of the target LED devices.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED display control chip. Background technique [0002] With the development of science and technology, more and more LED products are used in people's lives. The current LED display control chip design adopts the method of discrete devices, that is, constant current source chip + DC-DC power supply circuit + MOS switch (MOS The tube switch circuit is a circuit constructed by using the MOS tube gate to control the on-off of the MOS tube source and drain) + logic switch + logic drive to form the display control of the LED. [0003] In the prior art, there are many types of LED display control chip devices, low processing efficiency, high system complexity, and high system power consumption [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] An embodiment of the present invention provides an LED display control chip to at least...
