Abstract

This invention disclosed a multi-domain dynamic-driving backlight module and the method thereof. During different sub-frame time, this invention is implemented via varied combinations for on/off of the different color light sources in every backlight sub-regions of the backlight module and the different color light switches (as liquid crystal pixels for different colors) in the correspondent display sub-regions of the panel. For instance, as a red light source of a backlight sub-region is turn on, it is able to pass through the red light switch of a correspondent display sub-region but, meanwhile, is blocked by the red light switches of display sub-regions near the display sub-region. In other words, other display sub-region don't be influenced by the red light source. The similar method can be used for controlling other color light sources and light switches of the display, so that the backlight light sources for a specific display sub-region does not disturb the neighboring display sub-regions. Therefore, the interference of light field effect can be reduced, and it is not necessary to install light-separated units between backlight sub-regions as the conventional backlight module.

Description

200935098 IX. Description of the invention: [Technical field to which the invention pertains] </ RTI> In particular, the invention relates to a device for backlight driving and a method thereof, and a device for dynamic dynamic backlight driving and a method thereof. [Prior Art] = In the liquid crystal display device, the liquid panel of the liquid crystal display panel itself does not produce light, and it must be provided by the county to provide a silk-to-image image on the display panel. The _ secret is divided into a plurality of side areas and each side has a corresponding back wire, and the bribe, for example, subdividing the backlight to achieve the effect of inserting the black surface to reduce the liquid crystal display panel when displaying the dynamic image Shadow problem, or adjust the backlight of each partition with the display partition screen to achieve power saving. , the face, between the adjacent backlights, according to the distance between the S light source and its brightness does not have a _ light field, so that the different face requirements of the face display when the actual display image Mutual interference. The structure of the conventional display device is, for example, the first riding, in which the backlight is divided into three structures: the back wire and the display panel, and the three=source systems are respectively a backlight 121, a second backlight 122 and a third backlight 123, wherein: the backlight 121, 122 or 123 is - in fact not limited to a single-point source or a single line source - or a plurality of The same as the backlight module component (four) point light source or line light source, and the above display panel is divided into the first display area 1 corresponding to the first backlight 12 彳, the second backlight 122 ^ 。 light source 123. 1. The second display area is 彳. 2 and the first region 103 ' In other words, the light source required for the first display region 1 〇 1 is mainly provided by the March light source 121 &amp; the light source required for the second display region 2 is mainly provided by the first light source 122 The light source required for the third display area 彳Q3 is provided by the main third backlight 123, and the corresponding display area is utilized between the first backlight 121, the second backlight 122 and the third back 123. 101, 102, 103 required eyesight to adjust the intensity of the generated light source, for example, if the target brightness of the second display area like 200935098 is half of the target brightness of the first display area 1〇1 and When it is a quarter of the target brightness of the third display area 103, the brightness of the corresponding first backlight 121, the second backlight 122, and the third backlight 123 should be 2:1:4 after being quantized. When the first backlight 121, the second backlight 122, and the third backlight 123 are simultaneously turned on, the backlights 121, 122, and 123 corresponding to each of the display regions 101, 102, and 103 provide different brightness. Light source, but because of the first backlight 121, Effects of the field effect between the two light sources 122 and the third backlight backlight 123, i.e., the left foot each display area 01, 102, 103 may be disturbed by its neighboring area corresponding to the display backlight, such that the final

Cl ) to the corresponding first display area 10 彳, the second display area 1 〇 2 and the third display area 1 〇 3, the actual brightness is not the original target brightness, thus making the overall face coordination Become worse.

Φ

In addition, the present invention can also be applied to a monochrome display device. For example, each of the sub-light sources of the device of FIG. 3 adopts the same-color light source', and each of the sub-paste cells adopts a liquid crystal display capable of controlling the transmittance of the color light source. Prime. Taking the following steps S1 to S2 of the apparatus and the flowchart of FIG. 6 as an example: when the step S1 ′′, the first light source 221 and the third light source 223 are turned on; the first light source 222 is turned off, and the second optical switch unit 242 is turned off; In the case of S2", the second light source 222 is turned on; the first light source 221 and the third light source 223 are turned off; and the first optical switch unit 241 and the third optical switch unit 243 are turned off. Taking the first sub-display partition 201 as an example, in the step sr, since the second light source 222 has been turned off 'and therefore is not interfered by the second light source 222, in the step %, , because the first-sub-display partition 201 The optical switch unit 241 has been turned off and is not interfered by the second light 22 . Similarly, the second sub-display partition 202 is not interfered by the first light source 221 and the third light source 223, and the third sub-display partition 2Q3 is not interfered by the second light source 222. Because of riding, it is possible to achieve the backlight intensity of the partition in a monochrome display without causing adjacent backlights to interfere with each other. In addition to the red photon light source and the green photon light source as an example, the red light source, the green photon source and the blue sub-light source are also available. The sub-light source can also be selected from red photonic filament, county sub-system and blue. For example, the combination of the Xuanyuan source is composed of (4) photon light source... As long as the reward can be adjusted by the various sources, the coffee and the light will become the equivalent of the light. In addition, the present invention can be applied to a color liquid crystal display device or a general liquid crystal display device. 13 200935098 A general liquid crystal display device uses a timing-controlled display driving circuit to apply electric dust to the liquid crystal display panel to control each liquid crystal pixel. The transmittance, for the backlight module, requires an additional backlight drive circuit for backlighting and brightness control. In the implementation of the multi-region backlight control method of the present invention, when a sub-optical switch needs to be turned off, the transmittance of the crystal lens is lowered by the display of the voltage of the electric driver, and the optical switch is not It is necessary to display the voltage of the input circuit of the driving circuit to the liquid crystal pixel for display of the image. In summary, the multi-region dynamic backlight driving device and method of the present invention can cooperate with the opening and closing of the side light and the close and fine closing units to reduce the light field between the multiple backlight systems. Interference effect, shame makes each group of backlight wires from the backlight module pass through the liquid crystal cell, and can provide a corresponding display area to perform image t ' with a display effect closer to the target brightness, color contrast, and color saturation. The contrast between the bright and dark areas of the display is more significant, and the stereoscopic and realism of the image can be improved at the same time.
