Problems solved by technology

However, as far as the existing technology is concerned, no matter it is a traditional CRT display or a liquid crystal display, it is still unable to effectively save the power of the display itself according to the type of the displayed picture.
Although there is currently a method to save power on the display by building a timing shutdown system in the display to save power when the user leaves the display but forgets to manually turn off the display, but this method can only be used when the display is unattended. It achieves power saving effect during use, but it is difficult to achieve power saving effect when users frequently use the monitor
Therefore, existing display products face a bottleneck in power saving because it is difficult to save power on the display while the user is using the display.
In addition, the existing display products cannot save power for a partial screen of the display, so when the user only watches a partial screen of the display, the power consumption of the display still cannot be reduced

Embodiment Construction

[0038] Certain terms are used in the specification and subsequent claims to refer to particular components. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same component by different terms. This description and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The term "comprising" mentioned throughout the specification and subsequent claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device can be directly connected to the second device, or indirectly connected to the second device through other devices or connection means. "Electrically coupled" or "electrically...

Abstract

The invention discloses a display control system and an electronic device. The display control system includes a display unit and a timing control unit. The display unit includes at least one source driving unit and a gate driving unit. The source driving unit includes an output buffer unit, a plurality of switches and a register unit. The output buffer unit is used to output image signals or high impedance signals. The switches are used to receive the image signals or high impedance signals. The gate driving unit is used to output gate driving signals. The timing control unit is used for controlling the timing of the source driving unit and the gate driving unit. Through the display control system provided in the embodiments, a display save power when static images or partial static images are displayed.

Description

technical field [0001] The invention relates to a display control system and an electronic device, in particular to a display control system and an electronic device that can save power for the display according to the image signal characteristics of the image screen of the display. Background technique [0002] At present, display products are quite popular, and in response to the needs of users for work or entertainment, display technology is also constantly improving. Liquid Crystal Display (LCD) has gradually replaced traditional CRT displays due to its thinner appearance, low radiation pollution, and low production cost, and is widely used in notebook computers or personal digital assistants (PDA) and other mobile devices. [0003] As monitors have become an indispensable electronic product in daily life, the accumulated power consumption of monitors in every household is considerable. Since the implementation of energy saving and carbon reduction is the goal that cou...
