Embodiment Construction

[0024] In order to save power consumption, the present invention performs a new image recognition action, and the update action is only executed when a new image (or a different image) is found. Referring to FIG. 2(A) and FIG. 3(A), the operation of the present invention in a display system without a display memory and a display system including a display memory will be described below.

[0025] A display system mainly includes a host 21 , a driving circuit 22 , and a display panel 23 . After receiving an image signal from the host 21, the driving circuit 22 drives the display panel 23 to display image data. According to the invention, a newly received image signal is checked to determine whether the image signal represents a new image, ie different from the image being displayed on the display panel 23 . Once the image signal represents a new image, data updating of the display panel proceeds normally. On the contrary, the incoming data is blocked, and the last passing data...

Abstract

For reducing power consumption of a display, whether a currently received frame data is different from a currently displayed frame data or not is discriminated. If the currently received frame data is different from the currently displayed frame data, execute data refresh in a normal way. If the currently received frame data is not different from the currently displayed frame data, suspend data refresh for saving power.

Description

technical field [0001] The invention relates to a method for reducing power consumption of a display system, in particular to a method for performing new image recognition to reduce power consumption of a display system. The invention also relates to a display system with low energy consumption. Background technique [0002] A driver IC drives the display panel according to an image signal from the host to display input or updated image data, and its functional block diagrams can be referred to FIG. 1(A) and FIG. 1(B). The display device 12 can optionally have a built-in display memory 121 , such as a random access memory (RAM), for receiving images from a host 11 through a driver IC 122 and storing them in the form of pixel data arrays. Although in terms of interfaces such as CDP (continuous data protection) or red, green and blue RGB (RGB red, green and blue), the display data can be continuously sent to the display panel 123 at high speed without going through the displa...
