specific Embodiment approach

[0143] Specifically, according to another specific implementation manner, the external control signal includes a blank space control signal;

[0144] The step of setting the display data in advance by the setting module includes: setting the second display data in advance by the setting module, the grayscale value of the second display data is within a predetermined range;

[0145] The selection module selects the input module or the setting module to input the display data to the data input terminal according to the external control signal. The step includes: when the blank area control signal is valid, the bidirectional switch included in the selection module is controlled by the setting module. Inputting second display data to the data input terminal, when the blank area control signal is invalid, the bidirectional switch included in the selection module controls the input module to input display data to the data input terminal;

[0146] When the data input terminal is conn...

Abstract

The invention provides a data input unit, a data input method, a source drive circuit and a display device. The data input unit comprises an input module, a setting module and a selection module, wherein the setting module is used for presetting the display data; and the selection module is used for selecting the input module or the setting module to input the display data into the data input end according to an external control signal. The data input unit, the data input method, the source drive circuit and the display device provided by the invention are added with the setting module and the selection module, the setting module is used for presetting the display data corresponding to specific display needs, and the selection module is used for selecting whether to input the display data into the data input end from the setting module according to the external control signal; and a specific drive function is realized apart from normal drive function so as to improve the performance and display quality of a display device and improve the display quality.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a data input unit, a data input method, a source driving circuit and a display device. Background technique [0002] Source Driver IC (source driver integrated circuit) is an integrated circuit with specific functions used in display devices to analyze and process digital signals in a predetermined format and scan in predetermined order to send analog signals to each string of data lines. The existing data input unit only includes an input module (for example, it can be an input register) to input normal display data to the data input terminal, and cannot display a black screen on the display panel when there is a special display requirement (for example, when the machine is turned off, or when A gray scale picture is inserted in the blank area between two frames of display data to improve the display quality) correspondingly output specific preset display data to the source dri...
