Abstract

The embodiment of the invention discloses a source driving chip and a display device, and the source driving chip comprises a first pre-charging module which is used for pre-charging a first data signal when the voltage of the first data signal is greater than a preset reference voltage. The first data line is pre-charged to a first preset voltage and while the second data line is pre-charged to asecond preset voltage; when the voltage of the first data signal is smaller than the preset reference voltage, the first data line is pre-charged to a second preset voltage and the second data line is pre-charged to a first preset voltage, wherein the first preset voltage is greater than the second preset voltage. According to the source driving chip and the display device provided by the embodiment of the invention, the temperature of the source driving chip can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a source driver chip and a display device. Background technique [0002] As the size of the liquid crystal display panel becomes larger, the larger the size, the larger the in-plane resistance drop (RC loading). [0003] In order to ensure the charging effect, it is necessary to increase the efficiency of the source driver chip, which in turn makes the temperature of the source driver chip higher, that is, the heat generation is relatively serious, so the source driver chip is easily damaged. Contents of the invention [0004] Embodiments of the present application provide a source driver chip and a display device, which can reduce the temperature of the source driver chip and avoid damage to the source driver chip. [0005] An embodiment of the present application provides a source driver chip, which is applied to a display panel, where the display panel includes a...
