Abstract

The invention relates to a delay adjustment circuit and a method, and a display device. As that detect unit automatically detects the data signal edge and the clock signal edge and control the timingunit to record a plurality of groups of setup time and holding time, at that same time, the compute unit calculates a plurality of set-up time and holding time, obtains and feeds back the time information, thereby adjust the relative delay time of the output data signal and the clock signal according to the time information and the preset relative delay time, so as to satisfy the relative time requirement and improve the data transmission quality; and according to the different data transmission conditions, there are different preset relative delay time to adapt to achieve adaptive dynamic matching, meet the requirements of eye diagram under various data transmission conditions, and do not need too much manual debugging, save time and labor.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a delay adjustment circuit and method, and a display device. Background technique [0002] As the size and resolution of LCD TVs increase, more and more data needs to be transmitted. As a result, differential signals have become popular as a high-speed transmission protocol, and the quality of data transmission is also facing more severe tests. When the data transmission amplitude (the magnitude of the amplitude corresponds to the high level and low level of the data) meets the requirements, the relative time between the clock signal and the data signal is also very important. [0003] However, with the increase in the number of differential pairs and the thinning of the driver board, coupled with the increase in transmitted data, the quality of data transmission is getting worse and worse. In practical applications, the relative time is often too small to cause data transmissio...
