Liquid crystals are filled between the upper plate and the lower plate, and polarizing plates that linearly display visible light (natural light) are attached to both surfaces of the upper plate and the lower plate, respectively.

The color filter for displaying color is a thin film type optical component that extracts three colors of red, green, and blue from white light and enables them in fine pixel units. In hundreds of microns. A pixel has the same meaning as a pixel, and the pixel is a point of light and dark in the minimum unit constituting the image. The larger the number of pixels in the whole image, the more accurate and detailed reproduction screen can be obtained, which is expressed as 'high resolution'.

The pixel is composed of an RGB color space based on red, green, and blue, and may express different colors by optically mixing at least one of the red, green, and blue colors in the RGB color space.

One embodiment of performing color adjustment according to the present invention is to add a region including information on whether to apply color adjustment to the RGB data format constituting the pixel.

Table 1 shows an example of the pixel data format according to an embodiment of the present invention.

Bit: 1 8 8 8 Dimming Field Red field Green field  Blue field

Referring to Table 1, the pixel data format according to an embodiment of the present invention includes a DRGB including an area including information on whether to apply color adjustment and an area including information for expressing colors of red, green, and blue. It can be implemented as. The RGB color data format consists of 8 bits each, and each bit may be represented by 0 and 1. Therefore, red, which is composed of 8 bits, may cover 256 kinds of red series colors. Since the same is true for green and blue, a color space based on RGB can express approximately 1678 million colors.

When the area including the information on the color adjustment is composed of 1 bit, for example, when the '1' bit is set, it may indicate that the color adjustment is applied, and when the '0' bit is set, it may indicate no application. The definition of the bit value set in the dimming area may change the meaning of '1' and '0', and when the area is composed of two or more bits, it may represent more specific and detailed color adjustment information.

In the above embodiment, when 1 bit is set in the dimming area and color adjustment is applied to a corresponding pixel, color adjustment may be performed with a predetermined specific color. At this time, the color output to the area to be color adjusted may be customized by the user (custermizing).

Therefore, referring to the DRGB data format according to an embodiment of the present invention, when color adjustment is applied, a bit value set in the RGB region is not used to determine pixel color.

When the color adjustment according to an exemplary embodiment of the present invention is applied, when the pop-up window is output in the third area 202 in FIG. 5, except for the area 203 where the pop-up window is output in the third area 202. The color of the area may be adjusted to a predetermined color.

Another embodiment for performing color adjustment according to the present invention is to implement a different color by adjusting the bit value set in each RGB region when applying the color adjustment in the RGB data format constituting the pixel.

As described above, the basic color information constituting the pixel is represented by RGB, and as shown in Table 1, the pixel color data format is composed of regions including color information for each of red, green, and blue.

For example, the graphic module 182 that performs color adjustment requires that the pixel color of the area to which the color adjustment is to be applied is 1/2 of the original color so that the color adjustment is applied to a certain area of the display screen according to a user selection. It can be controlled to be expressed in another color having a saturation of a degree.

As described above in Table 1, the red region includes 256 red color information through 8 bits, and 256 color information can be expressed in various colors to enable saturation or contrast in the red color. . This may be equally applied to an area including green color and blue color information.

Therefore, when the user input signal is applied, the graphic module 182 may have a brightness, contrast, saturation, contrast, etc. of the bit value constituting the RGB region of the color data format constituting the pixel of the region higher than the original color. It can be set to display different colors. When the color adjustment according to another embodiment of the present invention is applied, when the pop-up window is output in the third area 202 in FIG. 5, except for the area 203 where the pop-up window is output in the third area 202. It can be expressed such that the saturation of the color of the region is reduced.

Dimming control through saturation reduction of about 1/2 is merely an example for describing an embodiment of the present invention, and the rate at which saturation is reduced may be customized by a user. In addition, the color adjustment of the region where the color adjustment is performed may be implemented not only with saturation but also with contrast, contrast, level adjustment, and the like, and may also be customized by the user.

In another embodiment of the present invention, as shown in FIG. 5, the graphics module 182 outputs the color of the pixel constituting the region 203 where the pop-up window is output in the third region 202 in the third region. It can be adjusted differentially with the remaining areas except the ones. For example, by comparing the RGB color constituting the pixel of the area to be emphasized with the original output color, the brightness, contrast, saturation, contrast, etc. may be adjusted to make it brighter than the original color. In this case, in contrast to the area to which dimming is applied, the visual effect may be increased by implementing color brightness, saturation, and contrast.

As described above, when local dimming control is used in a mobile terminal in which a plurality of independent applications are implemented by multi-division, by applying dimming so that the remaining regions other than a predetermined region where image graphics or menu text are displayed are darkened in a specific segmented region. Clearer information delivery becomes possible.

6 is a view for explaining another embodiment of an operating state of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 6, in an embodiment of the present invention illustrated in FIG. 5, dimming may be applied to all of the partitions 202 and 203 when an event of an application executed in an arbitrary partition area 202 occurs.

For example, when the pop-up window 203 is a message for notifying an operation error of an application executed in the partition 202, the region does not affect the operation of an application executed in other partitions 200 and 201. Color adjustment can be applied only at 202 and 203.

On the other hand, the pop-up window output from any of the plurality of divided regions of the display unit is not limited to being limited to the divided region in which the application is running, as shown in FIGS. 5 and 6.

7 is a view for explaining another embodiment of an operating state of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 7, when a specific event occurs in an application performed in an arbitrary partition area 202 and a popup window 203 is output, the popup window 203 may be a different partition area where another application is being executed. Can also be output over. Even in this case, the graphic module 182 may control the color adjustment to be applied only to the partition 202 where the event in which the color adjustment is executed occurs.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.
