Abstract

The embodiment of the invention provides an LED driving chip and an LED driving system. The LED drive chip comprises: a code rate detection module, which is used for detecting a code rate parameter corresponding to display data input to the LED drive chip by a previous-stage element; the data buffer module is used for caching the display data input to the LED driving chip of the current stage by the previous stage of element; the data encoding and decoding module is used for receiving the code rate parameter sent by the code rate detection module, extracting the display data from the data buffer module, and decoding the display data according to the code rate parameter to obtain decoded display data; and the display output module is used for controlling an LED lamp to display according tothe decoded display data so as to achieve the effect of dynamically decoding the display data.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of LED (Light Emitting Diode, light emitting diode), and in particular, to an LED driving chip and an LED driving system. Background technique [0002] With the rapid development of LED, more and more types of LED driver chips have begun to appear. [0003] At present, the commonly used controller will decode the video to get the display data, and send it to the LED driver chip at a fixed bit rate of 800KHz for display. Because it is controlled to send display data to the LED driver chip for display at a fixed code rate, the decoding method of the LED driver chip is also fixed. [0004] However, there have been controllers that adapt different code rates to send display data according to video images, and the fixed decoding method of commonly used LED driver chips can no longer satisfy the decoding of display data according to dynamic code rates, so there is an urgent need for a dynami...
