Problems solved by technology

In addition, when the display device transmits / processes high-bit pixel data, the amount of data required for internal transmission is relatively large, which is accompanied by high power consumption, resulting in unnecessary power consumption of the display device.

Embodiment Construction

[0048] The term "coupling" used throughout the specification of this case (including the scope of claims) may refer to any direct or indirect means of connection. For example, if it is described that a first device is coupled to a second device, it should be interpreted that the first device can be directly connected to the second device, or the first device can be connected through other devices or some kind of connection means. indirectly connected to the second device.

[0049] The number of pixel data bits transmitted inside the display device of the present invention can be dynamically changed and not fixed at 6 bits, 8 bits or 10 bits. Hereinafter, 6-bit or 8-bit pixel data is used as an example for illustration, but it is not limited thereto.

Abstract

The invention relates to a display device and a drive circuit thereof, a driving method of a display panel, and a display system. The display device comprises a time schedule controller and a data drive circuit. The time schedule controller outputs first pixel data according to input pixel data, wherein the color depth of the first pixel data is a first digit or a second digit less than the first digit. The data drive circuit receives the first pixel data and a notification signal; according to the notification signal, when the color depth of the first pixel data is the second digit, mapping is carried out on the first pixel data to generate second pixel data; and when the color depth of the first pixel data is the first digit, the first pixel data are direct used as the second pixel data and at least one drive voltage is generated based on the second pixel data, wherein the color depth of the second pixel data is the first digit.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a display device, a data driving circuit thereof, and a driving method of a display panel. Background technique [0002] Traditionally, the color depth of the pixel data input by the display device is a fixed number of bits, such as 6 bits, and then the display panel is driven by a data driving circuit. When the number of bits (color depth) of the pixel data is higher, the color effect of the displayed picture is more detailed and better. [0003] However, general users do not need high-bit pixel data when enjoying dynamic images. As far as the dynamic picture is concerned, since the picture is constantly changing, the human eye cannot detect or pay attention to the difference in picture color resolution (such as 6bits and 8bits). Compared with static pictures, such as viewing color pictures, the color resolution of 6bit pixel data and the color resolution of 8bit pixel data ...
