Problems solved by technology

However, when performing spread spectrum processing on the clock signal, due to the limitation of the spread spectrum processing process and the normal transmission requirements of the display data, the dispersion of EMI energy after spread spectrum is very limited, and it is easy to have insufficient spread spectrum effect and it is difficult to meet EMI. Situation required

Abstract

The present application discloses a timing control chip, a display drive component, and a display device, wherein the timing control chip includes at least two sets of mutually independent spread spectrum circuits, and the spread spectrum circuits are configured to convert an initial clock signal into a spread spectrum clock signal, so that The sum of the signal strengths of all the clock signals in the timing control chip at any frequency after conversion is less than or equal to the preset strength threshold corresponding to the frequency. The technical solution of the present application improves the spread spectrum effect, thereby ensuring that the display device can better meet the requirements of electromagnetic interference.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a timing control chip, a display driving component and a display device. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. With the improvement of living standards, large-size, high-resolution, high-frame-rate display devices are becoming more and more popular. drive components, and output a clock signal from a timing control chip (Timer Control Register integrated circuit, TCON IC) in the display drive component to a data driver IC (Data Driver IC) and a scan driver chip (Gate Driver IC) in the display drive component, Realize the display of the image. As the data involved in the display process is getting larger and larger, in order to ensure the transmission of all effective display data within a limited time, usually the TCON IC will output two ...
