Embodiment Construction

[0035] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0036] see image 3 , in an exemplary embodiment, a signal transmission lock-out processing method is applied to a display device, and the display device includes a front-end motherboard chip and a display driver chip. The method for processing the loss of signal transmission lock can be executed by the front-end motherboard chip in the display device, and can include the following steps:...

Abstract

The invention relates to a method and a device for processing loss-of-lock of signal transmission. The method for processing loss-of-lock of signal transmission is applied to display equipment. The display equipment comprises a front-end mainboard chip and a display screen driving chip. The method comprises the steps of acquiring a transmission locking signal outputted in the display screen driving chip, and performing monitoring on the transmission locking signal; adjusting the amplitude of an output signal of the front-end mainboard chip or the strength of a high-frequency component in the output signal when the transmission locking signal is monitored to be invalid; and enabling the transmission locking signal to be recovered to valid from invalid through the adjustment. The working stability of the display equipment can be improved by adopting the method and device provided by the invention for processing loss-of-lock of signal transmission.

Description

technical field [0001] The present disclosure relates to the technical field of signal processing, and in particular to a method and device for processing out-of-lock signal transmission. Background technique [0002] At present, large screens have become the mainstream of display devices (such as television devices). However, due to the limitations of structure and pins, large screens will use longer transmission lines, so that the front-end mainboard chip 100 in the display device can be transmitted through the transmission line. Signal transmission between the display driver chip 200, such as figure 1 shown. [0003] With the increase of the screen in the display device, the transmission line will not only grow correspondingly, but also have multiple bends, which makes the consistency of the transmission line itself worse, resulting in a large attenuation of the signal during transmission, that is, It is manifested as the deterioration of the eye diagram corresponding t...
