Abstract

The invention provides a display panel control circuit, a display panel and a display device.The display panel control circuit comprises a first chip circuit, a plurality of second chip circuits and a signal repairing circuit, and the signal repairing circuit is used for repairing the first chip circuit when communication connection is established between the first chip circuit and the second chip circuits. And the signal repair circuit receives feedback electric signals sent by the plurality of second chip circuits, performs repair according to the feedback electric signals to generate repair electric signals, and sends the repair electric signals to the first chip circuit, so that the first chip circuit judges the communication state with the second chip circuits according to the repair electric signals. The signal repairing circuit generates a repairing electric signal according to the feedback electric signal, and the first chip circuit judges communication with the second chip circuit according to the repairing electric signal, so that attenuation and distortion caused by long-distance transmission of the feedback electric signal or transmission of a plurality of electronic components are avoided. Therefore, the first chip circuit is prevented from misjudging communication with the second chip circuit.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel control circuit, a display panel and a display device. Background technique [0002] Display technology has always been one of the important research directions in display devices, and the function of displaying images in a display device is usually implemented by a display panel. In the display panel, when transmitting data between some circuits, a point-to-point (Point To Point, P2P) protocol is usually used, and one of the characteristics of the P2P protocol is that there is no clock (Clock) signal, that is, a feedback electrical signal is required It is used to judge whether the communication between the circuits is normal. [0003] Due to the existence of many circuits in the display panel, the feedback electrical signal is attenuated due to the transmission distance during transmission in the circuit, or the multiple electrical connections of ele...
