DISPLAY CONTROL METHOD AND DISPLAY DEVICE USING THE DISPLAY CONTROL METHOD

A display control method of a display device involves detecting color characteristic parameters of one or more images to be displayed. The color characteristic parameters include RGB values that are compared with predetermined RGB values to obtain a comparison result. A working status of the color engine is controlled according to the comparison result.

DETAILED DESCRIPTION

Reference will be made to the drawings to describe various embodiments.

FIG. 1is a schematic block diagram of an embodiment of a display device10, which includes a display control system100. The display device10further includes a processor110, a storage120, a display130, and a color engine140. The display device10can be a smart phone, a mobile Internet device (MID), or other similar device.FIG. 1shows one example of the display device10, and the display device10can include more or fewer components than those shown in the figure, or have a different configuration of the components. The color engine140converts RGB color space of an image into HSI color space, where R represents red, G represents green, B represents blue, H represents hue, S represents saturation, and I represents intensity. The color engine140modulates the hue, saturation, or intensity of the image displayed on the display130to make the images displayed on the display device10sharper and clearer, thereby increasing visual quality of the displayed images.

The display control system100can include a plurality of programs in the form of one or more computerized instructions stored in the storage120and executed by the processor110to perform operations of the display device10. In one embodiment, the display control system includes a detection module101, a comparison module103, and a control module105. In general, the word “module”, as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language, such as, Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an erasable programmable read only memory (EPROM). The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable medium include CDs, DVDs, BLU-RAY, flash memory, and hard disk drives.

The detection module101detects color characteristic parameters of one or more images to be displayed on the display130. The color characteristic parameters comprise RGB values of the one or more images. The RGB values comprise an R value, a G value, and a B value of the one or more images. In one embodiment, the detection module101obtains the RGB values via a specific software program, such as a color extractor program of a Photoshop® application.

The comparison module103compares the RGB values of the images with corresponding predetermined RGB values and outputs a comparison result. The predetermined RGB values comprise a predetermined R value, a predetermined G value, and a predetermined B value, each of which is stored in the storage120. The predetermined RGB values are set within a value range of 0-255. In one embodiment, as shown inFIG. 2, the display device10provides a parameter setting interface for manually setting the predetermined RGB values.

The parameter setting interface132is activated by an application icon displayed on the display130or by a physical key arranged on the display device10. The parameter setting interface132includes RGB brightness parameter boxes for setting the R value, G value, and B value. The predetermined RGB values are input into the RGB brightness parameter boxes via an input/output (I/O) device (not shown) such as a touch panel or a keyboard of the display device10.

The control module105controls a working status of the color engine140according to the comparison result. In one embodiment, when the comparison result indicates that at least one of the R, G, and B values of the color characteristic parameters of the image is less than the predetermined R, G, and B values, respectively, the color engine140is activated by the control module105to process the one or more images to be displayed. When the comparison result indicates that each of the R, G, and B values of the color characteristic parameters of the image is greater than the predetermined R, G, and B values, respectively, the color engine140is turned off by the control module105.

FIG. 3shows a flowchart of one embodiment of a control method of the display device10. Depending on the embodiment, additional steps may be added, others removed, and the ordering of the steps may be changed.

In step S201, the detection module101detects color characteristic parameters of one or more images to be displayed on the display130. The color characteristic parameters comprise RGB values. The RGB values comprise an R value, a G value, and a B value. In one embodiment, the detection module101obtains the RGB values via a specific software program, such as a color extractor program of a Photoshop® application.

In step S203, the comparison module103compares the RGB values of the images with predetermined RGB values and outputs a comparison result. The predetermined RGB values include a predetermined R value, a predetermined G value, and a predetermined B value, each of which is stored in the storage120. The predetermined RGB values are set within a value range of 0-255.

In step S205, the control module105controls a working status of the color engine140according to the comparison result. In one embodiment, when the comparison result indicates that at least one of the R, G, and B values of the color characteristic parameters of the image is less than the predetermined R, G, and B values, respectively, the color engine140is activated by the control module105to process the one or more image to be displayed. When the comparison result indicates that each of the R, G, and B values of the color characteristic parameters of the image is greater than the predetermined R, G, and B values, respectively, the color engine140is turned off by the control module105.

In summary, the control method for the display device10automatically detects whether an image needs to be processed by the color engine140according to color characteristic parameters of the image. When the image to be displayed does not require to be processed, the color engine140is turned off. Thus, the display device10consumes less power.
