Abstract
The invention provides a method for promoting the brightness of a 3D (three-dimensional) television image. By carrying out technical processing of regulating a partition scanning time sequence and removing an inserted black frame for a TCON (Time sequence Controlling) panel, the method can solve the problem of insufficient brightness of an image of a liquid crystal module with backlight blinking in a 3D mode in a backlight multi-partition scanning manner; besides, the standard of the backlight operating manner of the liquid crystal module is unified and development time of the liquid crystal module and a shutter 3D television is shortened.
Description
Technical field
The present invention relates to the method for a kind of 3D of lifting television image brightness, particularly relate to a kind of method that is applicable to promote the brightness of shutter 3D television image.
Background technology
The 3D stereo technology of 3D stereoscopic TV mainly contains two kinds of polarization type (active) and shutters (being passive type), shutter 3D stereo technology utilizes the left-right switch of glasses and the left-right frames timed delivery of television image to replace, make eyes see the different pictures of quick switching, from so produce stereopsis brain.The liquid crystal module group backlight of shutter 3D LCD TV great majority under 3D pattern adopt the working method of subarea-scanning (Scanning), part adopts the working method of black plug frame backlight flicker (Blinking), the working method backlight under 3D rendering need to liquid crystal display screen TCON(sequencing control) sequential of plate requires the normal display effect of consistent guarantee 3D rendering.
Low and middle-end module in TV industry transfers producer's self-control exploitation to by module supplier, module supplier provides liquid crystal glass base (OPEN CELL), the backlight design of company's self-control module adopts 8 larger subarea-scanning modes of market share accounting, scanning sequence requirement backlight according to Open Cell under 3D rendering, the duty ratio (Duty) of 8 subregion scanning backlight is less than 20%, the drive current of backlight lamp bar needs to improve, while making backlight lamp bar brightness be 2D 2.5 times.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for a kind of 3D of lifting television image brightness.
The technical solution used in the present invention is as follows: a kind of method that promotes the brightness of 3D television image, its concrete grammar is: adjust the black plug two field picture under 3D stereo-picture.
As the present invention is further improved, cancel the black plug two field picture under 3D stereo-picture.
As the present invention is further improved, the black plug two field picture under 3D stereo-picture is changed to the image keeping before black frame.
As the present invention is further improved, described method also comprises the duty ratio that improves LED lamp bar.
As the present invention is further improved, the concrete grammar that improves the duty ratio of LED lamp bar is: backlight lamp bar is divided into upper and lower 2 field flickers, and upper field flicker sequential is than lower field flicker sequential time delay 2.1ms ~ 2.5ms.
As the present invention is further improved, described 2 field flicker scan modes are that former 8 subarea-scannings are divided into Shang Siqu is bright, and Xia Si district is dark, and Shang Si district is dark, the mixed sweep that Xia Siqu is bright.
As the present invention is further improved, described method also comprises, to the optimization process in image quality.
As the present invention is further improved, the concrete grammar of the optimization process in image quality is: by the image quality parameters such as filter of the luminance raising of picture signal, black level extension and vertical direction being optimized to processing under 3D pattern.
Compared with prior art, the invention has the beneficial effects as follows: by the enforcement of this patent, can solve under multi partition scan mode backlight, there is the liquid crystal module of flicker backlight in the problem of 3D pattern hypograph luminance shortage, the working method backlight of liquid crystal module is sought unity of standard simultaneously, shortened the development time of liquid crystal module and shutter stereoscopic TV.
Accompanying drawing explanation
Fig. 1 is the wherein sequencing control figure of the lifting 3D rendering brightness of an embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of method that promotes the brightness of 3D television image, its concrete grammar is: adjust the black plug two field picture under 3D stereo-picture.
The liquid crystal module of flashing mode require the black plug frame of TCON control board under 3D stereo-picture be according to " the left black right side is black " mode provide view data (be frame per second 60Hz, the left two field picture 4.165ms of the right two field picture 4.165ms-of left two field picture 4.165ms-black plug frame 4.165ms-black plug frame 4.165ms-... circulation provides view data).By black plug two field picture time shorten or after cancelling, can promote image brightness.
In this specific embodiment, cancel the black plug two field picture under 3D stereo-picture, and by the black plug two field picture under 3D stereo-picture change to keep before black frame a left side (or right) two field picture.For guaranteeing (to keep the switching time of the right and left eyes of shutter type 3 D spectacles identical with the frame per second of 3D rendering with the synchronous of 3D glasses, be to be switching time 8.33ms, one-period is 16.7ms), the mean flow rate of its picture with picture material under 3D pattern also just promotes thereupon.
Described method also comprises the duty ratio that improves LED lamp bar.
The concrete grammar that improves the duty ratio of LED lamp bar is: backlight lamp bar is divided into upper and lower 2 field flickers, be upper and lower halfth district bright 4.7ms respectively, dark 3.63ms, upper field flicker sequential is than lower field flicker sequential time delay 2.1ms ~ 2.5ms, after the bright 2.1ms of upper half, bottom half is bright, and after the dark 2.1ms of upper half, the dark mode of bottom half is worked.
Described 2 field flicker scan modes are that former 8 subarea-scannings are divided into Shang Siqu is bright, and Xia Si district is dark, and Shang Si district is dark, the mixed sweep that Xia Siqu is bright.In this specific embodiment, LED lamp bar bright 4.7ms under 3D pattern as requested, dark 3.63ms, the duty ratio that LED lamp bar is worked under 3D pattern has brought up to 57%, far above the performance of duty ratio less than 20% before.By improving the duty ratio of LED lamp bar, it is promoted in the brightness under 3D rendering.
For further avoiding the picture crosstalk problem of right and left eyes under 3D state, described method also comprises, to the optimization process in image quality.
The concrete grammar of the optimization process in image quality is: by under 3D pattern, the image quality parameters such as filter of the luminance raising of picture signal, black level extension and vertical direction being optimized to processing, to eliminate the crosstalk phenomenon of 3D rendering.
