Abstract

The invention provides a data driving chip and a display device. The data driving chip comprises: a latch module, which is used for receiving current display data, latching the current display data, and outputting the current display data after the current display data is latched; and an output module, which is used for outputting the current display data output by the latch module to a display panel. The latch module is further used for clearing the current display data latched in the latch module when the output module outputs the current display data. According to the data driving chip provided by the invention, the number of the latch modules is greatly reduced, so that the size of the data driving chip can be effectively reduced; meanwhile, the transmission path of the current displaydata in the data driving chip is simplified, so that the transmission rate of the current display data is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a data driving chip and a display device. Background technique [0002] In the prior art, a data driving chip usually includes two groups of latch modules: a first group of latch modules and a second group of latch modules. Among them, the first group of latch modules is used to latch the display data of the N-1th row when the N-1th rising edge of the control signal arrives; the first group of latch modules is also used to When the first rising edge arrives, the display data of row N-1 is transferred to the second set of latch modules, and the display data of row N is started to be received; wherein, N is a positive integer greater than 1. Since the display data of row N−1 is stored in the second group of latch modules, when the Nth falling edge of the control signal arrives, the second group of latch modules outputs the display data of row N−1 to the display panel. ...
