Abstract

The embodiment of the invention discloses a driving chip for a display device and a display device. The driving chip comprises a shift register, a data receiver, a data register, a data processor, a level converter, a digital-to-analog converter, and an output buffer. The data processor is electrically connected with the data register and comprises n input channels and m output channels. Any input channel is electrically connected with the m output channels. The data processor is used for controlling any input channel to be communicated with one output channel according to a pre-stored control instruction in order that any input channel outputs received corresponding channel data via the output channel communicated with the any input channel, wherein the n output channels communicated with the n input channels output effective channel data, and the (m-n) output channels not communicated with any input channel output no channel data. The data processor may flexibly adjust the sequence of the output channels and prevent a problem of display abnormality caused by erroneous wire connection of the driving chip.

Description

technical field [0001] Embodiments of the present invention relate to display driving technologies, and in particular, to a driving chip for a display device and a display device. Background technique [0002] The driver chip of the existing liquid crystal display module has an output channel, wherein the driver chip transmits the data signal to the corresponding data line through the output channel, and the driver chip transmits the gate signal to the corresponding gate line through the output channel. [0003] It is known that the number of data lines and gate lines of a liquid crystal display device is large, and the corresponding number of output channels of the driver chip is large. When the driver chip drives the gate lines, a part of the output channels may be selected to output the gate signal, and the driver chip When driving the data lines, some of the output channels may be selected to output data signals, so the output channels of the driver chip output correspon...
