Abstract

The invention provides a method and a device for identifying signal transmission integrity. The method for identifying signal transmission integrity is applied to any sending unit in a time schedule controller, the sending units correspond to receiving units of a source electrode driving circuit one by one, and the method comprises the following steps: calculating signals sent by the sending units by adopting first registers in the sending units, obtaining a summarized value of the sent signals, and recording the summarized value as a first sum check code; calculating the signals received by the receiving unit by adopting a second register in the receiving unit, obtaining a summary value of the received signals, and recording the summary value as a second sum check code; and calculating a difference value between the first sum check code and the second sum check code. According to the method and the device for identifying signal transmission integrity provided by the invention, whether the wiring layout of the display panel meets the requirement of signal complete transmission or not can be conveniently simulated in advance, and distortion of a display image is prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for identifying signal transmission integrity. Background technique [0002] A display device generally includes a display panel and a driving circuit for driving the display panel. The driving circuit includes a timing controller, a gate driving circuit and a source driving circuit. In the related art, the timing controller includes a plurality of sending units, and the source drive circuit includes a plurality of receiving units, and the sending units correspond to the receiving units one by one, and the receiving units correspond to the columns of pixels on the display panel. Units are connected one by one. When it is necessary to control the display panel to display images, each sending unit in the timing controller can send a signal to the corresponding receiving unit, so that each receiving unit can input to a column of pixel units connected on the dis...
