Abstract
The invention provides an RGBW display based display screen and a display control device thereof. The display control device comprises a backlight source and a light source driving chip; the backlight source comprises a red light emitting source, a blue light emitting source and a green light emitting source; and the light source driving chip comprises a control unit and a detecting unit, the detecting unit sends a detecting signal to the control unit after it is detected that image data which needs displaying is pure-color image data, and after receiving the detecting signal, the control unit increases the brightness of the light emitting source corresponding to the image color to enhance the brightness of the image color.
Description
Technical field
The present invention relates to field of display devices, more particularly, to a kind of display screen being shown based on RGBW and its display control dress
Put.
Background technology
The pixel of the at present general on the market LCDs being shown based on RGB includes three sub-pixels R, G, B, three
Sub-pixel is arranged side by side, and the pixel arrangement of the display screen being shown based on RGBW is：Four sub-pixels R, G, B, W form a square
Shape arranges, area and two pixel areas occupied of the display screen being shown based on RGB that described four sub-pixels R, G, B, W take
Equally, the area occupied of the single sub-pixel of the display screen being shown based on RGBW is 1/4, and the liquid crystal display being shown based on RGB
The area occupied of the single sub-pixel of screen is 1/3, so, from the point of view of the single sub-pixel of pure color, RGBW pure color aperture opening ratio is about
The 75% of RGBW, therefore, the LCDs that shown based on RGBW shows during pure color it is possible that the partially dark situation of picture.
Content of the invention
For overcoming the deficiencies in the prior art, the present invention provide a kind of prevent from showing partially dark display screen during solid-color image and its
Display control unit.
The present invention provides a kind of display control unit, is applied to a display screen showing based on RGBW, described display control
Device includes backlight and a light source driving circuit, and described backlight includes emitting red light source, blue-light-emitting source and green emitting
Source, described light source driving circuit includes a control unit and a detecting unit, described detecting unit be used for detect need aobvious
For sending detection signal after solid-color image data to described control unit, described control unit is used for receiving the view data shown
The brightness to strengthen the color of described image for the light emitting source of the color of corresponding described image is lightened to after described detection signal.
Further, described detecting unit is used for receiving the view data needing display and according to the described figure needing display
Whether the view data shown in the brightness value of three kinds of primary colours of data to judge described needs is solid-color image.
Further, described control unit is used for the size of the electric current to described light emitting source by control input to adjust
State light emitting source.
Further, described red light-emitting source, described blue light emitting source and described green luminescence source are light emitting diode.
The present invention also provides a kind of display screen showing based on RGBW, and described display includes above-mentioned display control
Device processed.
Further, described display screen is the display screen of mobile phone.
Further, described display screen is the display screen of computer.
In the present invention, described light source driving circuit is after detecting and needing to show solid-color image, by controlling red sending out
The brightness of light source, blue-light-emitting source and green emitting source strengthening the brightness of solid-color image, thus it is partially dark to improve RGBW pure color
Problem, the viewing of lifting display screen regards effect.
Brief description
The system block diagram of the display control unit better embodiment of the display screen that Fig. 1 is shown based on RGBW for the present invention.
Specific embodiment
Now, it is described more fully present inventive concept hereinafter with reference to accompanying drawing, the present invention shown in the drawings
The exemplary embodiment of design.According to following illustrative embodiment described in more detail with reference to the accompanying drawings, present inventive concept
Advantages and features and make they realize method will be apparent from.It is to be noted, however, that present inventive concept is not limited to
Following illustrative embodiment, and can be implemented in a variety of manners.Therefore it provides exemplary embodiment is only for open
Present inventive concept and allow skilled in the art realises that the category of present inventive concept.In the accompanying drawings, the embodiment of present inventive concept
It is not limited to specific example provided herein.
Unless otherwise defined, otherwise all term used in embodiment disclosed by the invention (include technical term and
Scientific terminology) be there is the implication identical implication being generally understood that with the those of ordinary skill of the technical field belonging to the present invention,
And it is not necessarily limited to known specific definitions when the description present invention.Therefore, these terms can include this moment it
The equivalent terms created afterwards.It will be further understood that, these terms such as defined in the dictionary being usually used should be explained
For have with this specification in and the background of prior art under their implication identical implication, and unless here clear and definite this
Sample defines, and otherwise not to be explained with Utopian or excessively formal meaning.
Refer to Fig. 1, the display control unit better embodiment of the display screen that the present invention is shown based on RGBW includes one
Backlight 10 and a light source driving circuit 30.
Described backlight 10 includes emitting red light source 11, blue-light-emitting source 13 and green emitting source 15, in the present embodiment,
Described red light-emitting source 11, described blue light emitting source 13 and described green luminescence source 15 are light emitting diode.
Described light source driving circuit 30 includes a control unit 31 and a detecting unit 33, and described detecting unit 33 is used for connecing
Receive the view data needing display and according to the brightness value of three kinds of primary colours of the described view data needing display judges
Whether the view data needing display is solid-color image.For example described need display view data three kinds of primary colours (red, green,
Blue) brightness value be (0,0,255), (0,255,255), (0,0,0), (0,255,0), (255,0,0), (255,0,255),
(255,255,0) or (255,255,255), judge that the described view data needing display is solid-color image.Described detecting unit
33 detect described need display view data be a solid-color image after send a detection signal to described control unit 31,
Described control unit 31 lightens the light emitting source of the color of corresponding described solid-color image to strengthen after receiving described detection signal
The brightness of the color of described image.For example solid-color image is redness, and described control unit 31 lightens described emitting red light source 11, red
After light transmission red color resistance (not shown), brightness is bigger, needs the brightness of the color of the image of display such that it is able to reinforcement.
The present invention detect need show solid-color image after, by control emitting red light source 11, blue-light-emitting source 13 and
The brightness in green emitting source 15, to strengthen the brightness of solid-color image, thus improving the partially dark problem of RGBW pure color, lifts display screen
Viewing regard effect.The display screen of the present invention can be used for mobile terminal it is also possible to apply and computer or television display screen.
Although illustrate and describing the present invention with reference to specific embodiment, it should be appreciated by those skilled in the art that：
In the case of without departing from the spirit and scope of the present invention being limited by claim and its equivalent, can here carry out form and
Various change in details.
