Particularly, the brightness impression unit 3 of such as light sensor and so on can ambient light intensity near sense terminals equipment, and produces the detection signal relevant to current environment light intensity.Control module 2 receives this detection signal from brightness impression unit 3, and judges whether this detection signal exceedes default threshold value.Here, if detection signal exceedes default threshold value (variable, and arrange based on empirical value), then control module 2 judges that terminal device is in brighter environment, and therefore control module 2 controls display screen 1 and enters highlighted display mode.In addition, if detection signal does not exceed default threshold value, then control module 2 judges that terminal device is in not too bright environment.Now, control module 2 controls display screen 1 and is in general display mode.In addition, the terminal device shown in Fig. 1 can not comprise brightness impression unit 3.Now, can manually change the parameters such as display is arranged by user to make control module 2 control display screen 1 to switch between general display mode and highlighted display mode.
Here, under general display mode, control module 2 provides the picture signal with original view data to the first unit display unit of display screen 1 and/or the second unit display unit.In addition, under highlighted display mode, control module 2 provides the picture signal with original view data to the first unit display unit of display screen 1, and provides the picture signal with default brightness to the second unit display unit.Here, the brightness preset is the maximum brightness that the second display unit can show.In addition, the brightness preset can also be the higher brightness that the second display unit can show.Such as, when utilizing 8 bit data (0-255) to represent the brightness of each R, G, B sub-pixel of display screen, the brightness preset can be 255 or between 200-255.
By above-mentioned configuration, when needs make terminal device with higher brightness displaying contents, original data content is shown by utilizing the first unit display unit in the LCD Panel of terminal device, and utilize the second unit display unit display high-brightness content corresponding with the first unit display unit, the overall brightness increasing LCD Panel thus with user is seen clearly.
With reference to Fig. 2-4, the display and control performed according to pixel layout and the control module 2 of the display screen of different embodiments of the invention will be described respectively below.
Fig. 2 is the schematic diagram of the diagram pixel layout of the display screen of terminal device according to an embodiment of the invention.
Below, be described for TFT (Thin Film Transistor (TFT)) LCD Panel.Here it is to be noted that it the present invention can also be applied to the LCD Panel of such as SLCD and so on.
The display screen 1 of such as TFT LCD Panel and so on can comprise the pel array be made up of multiple primary colors sub-pixel (e.g., RGB sub-pixel) usually, and wherein each group RGB sub-pixel forms the display pixel of display screen 1.
As shown in Figure 2, each R, G, B sub-pixel of display screen all comprises the secondary sub-pixel (the first unit display unit and the second unit display unit) of two corresponding primary colours according to an embodiment of the invention.Particularly, for R sub-pixel, R sub-pixel comprises two R time adjacent level sub-pixels, and for G sub-pixel, G sub-pixel comprises two G time adjacent level sub-pixels, and for B sub-pixel, R sub-pixel comprises two B time adjacent level sub-pixels.That is, different from the situation that display pixel single in TFT LCD Panel in prior art comprises single R, G, B sub-pixel respectively, comprise two R level sub-pixels, two G level sub-pixels and two B level sub-pixels respectively according to the single display pixel of the display screen 1 of the embodiment of the present invention, and two R level sub-pixels, two G level sub-pixels and two B level sub-pixels form individual R, G, B sub-pixel of display pixel respectively.
Here, R, G, B level sub-pixel are all the liquid crystal pixels with TFT drives structure (TFT transistor), and because the structure of the liquid crystal pixel with TFT drives structure is known to those skilled in the art, be therefore omitted here the description of the structure to R, G, B level sub-pixel.In other words, R, G, B level sub-pixel are structurally identical with R, G, B sub-pixel, and equal corresponding R, G, the area sum of B level sub-pixel with the area of R, G, B sub-pixel.Here, the area of R, G, B level sub-pixel can be identical or not identical.According to above-mentioned configuration, if when the area of single display pixel is constant, owing to being the twice of number of corresponding R, G, B sub-pixel in TFT LCD Panel of the prior art according to actual R, the G of the embodiment of the present invention, the number of B level sub-pixel, therefore according to the better exquisiteness of display effect of the display screen 1 of the embodiment of the present invention.
In this case, if control module 2 controls under display screen 1 is in general display mode, then control module 2 provides normal picture signal at each display pixel to display screen 1.Namely, control module 2 provides the picture signal of the view data with original (normally) to two secondary sub-pixels of R (or G or B) in each R (or G or the B) sub-pixel of display screen 1.In this case, identical with display screen of the prior art according to the display effect of the display screen 1 of the embodiment of the present invention.
In addition, under control module 2 is in highlighted display mode based on the detection signal of brightness impression unit 3 or the input control display screen 1 of user, then control module 2 is while providing the picture signal with original (normally) view data to one of two secondary sub-pixels of R (or G or B) in each R (or G or the B) sub-pixel of display screen 1, the picture signal with predetermined luminance (e.g., the high brightness of 200-255) is provided to another R (or G or B) the secondary sub-pixel in two secondary sub-pixels of R (or G or B).
Here, suppose that the backlight illumination of display screen 1 is 1000nit, and the transmittance of R (or G or the B) color filter of R (or G or B) secondary sub-pixel is 10%.In this case, if certain the R sub-pixel in the display screen of prior art is based on picture signal (R127, the transmittance representing R sub-pixel is 50%) when showing, the brightness of its R sub-pixel can be expressed as 1000*50%*10%=50nit.But, according to embodiments of the invention, when display screen 1 is in hi-bright mode, one in R sub-pixel R level sub-pixel shows based on picture signal (R127), and another R time level sub-pixel shows based on having default brightness (as R255, representing that the transmittance of R sub-pixel is the maximum brightness of 100%) picture signal.In this case, if the area of two R level sub-pixels is identical, then the brightness of whole R sub-pixel is (1000*50%*10%+1000*100%*10%)/2=75nit.Here, due under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, identical with to the process of R sub-pixel to the process of G with B sub-pixel, no longer repeated description is carried out to it here.
Be not difficult to find out from foregoing description, under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, when the brightness of backlight is constant, when display image signals R127, the brightness of R sub-pixel improves 50%.And G and B sub-pixel also has identical effect.In addition, when the brightness that the picture signal with raw data represents is darker, the effect of luminance raising is more obvious.Therefore, under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, display screen 1 can provide obviously higher brightness, and user also can the content of clearly display on browse displays screen 1 in outdoor thus.Here, under hi-bright mode, because the brightness of R, the G of the picture signal for exhibit high brilliance, B level sub-pixel is very high, therefore through these R, G, B level sub-pixel light through colour mixture be white light, this can affect a little R, the G for showing raw data, B level sub-pixel color thus cause colour cast.But due to when the content of outdoor viewing display screen 1, colourity and saturation degree that user often wishes to see shown content clearly and can not pay close attention to display screen 1, therefore can not affect the use of user in outdoor.
In addition, according to another embodiment of the invention, the area of R, G, B level sub-pixel can not be identical.Such as, under hi-bright mode for showing R, the G of raw data, the area of B level sub-pixel can be larger than the area of the R of the picture signal for exhibit high brilliance, G, B level sub-pixel to provide color restoration capability better.In addition, under hi-bright mode for showing R, the G of raw data, the area of B level sub-pixel can be less of than the area of the R of the picture signal for exhibit high brilliance, G, B level sub-pixel to provide higher brightness etc.
In addition, according to another embodiment of the invention, the transmittance of color filter that R, G, B level sub-pixel (TFT liquid crystal pixel) comprise also can be different.Such as, R, the G for showing original data content under highlighted display mode, B level sub-pixel and under highlighted display mode with high brightness carry out R, the G shown, B level sub-pixel area identical when, for showing R, the G of original data content under highlighted display mode, the transmittance of the color filter of B level sub-pixel can be 12% and transmittance for R, the G carrying out showing with high brightness under highlighted display mode, B level sub-pixel color filter can 8% (in prior art, corresponding color filter transmittance be generally 10%).Like this, if under being in general display mode according to the display screen 1 of the embodiment of the present invention, certain R sub-pixel of this display screen 1 shows based on picture signal (R127), and the brightness of its R sub-pixel can be expressed as (1000*50%*12%+1000*50%*8%)/2=50nit.In addition, when display screen 1 is in hi-bright mode, one in R sub-pixel R level sub-pixel shows based on picture signal (R127), and another R time level sub-pixel is based on having default brightness (as R255,) picture signal is when showing, then the brightness of whole R sub-pixel is (1000*50%*12%+1000*100%*8%)/2=70nit.The benefit done like this is: under highlighted display mode, carry out show R by being used for high brightness, G, the transmittance of the color filter of B level sub-pixel reduces slightly, and improve slightly the R being used for showing original data content under highlighted display mode, G, the transmittance of the color filter of B level sub-pixel can make the display effect of display screen 1 under general display mode change, and the R that can suppress slightly for carrying out showing with high brightness under highlighted display mode, G, the brightness of B level sub-pixel, alleviate the R for carrying out showing with high brightness thus, G, the brightness of B level sub-pixel is to the R for showing original data content, G, the impact of the content shown by B level sub-pixel, namely alleviate by the R for carrying out showing with high brightness, G, the impact of the colour cast that the brightness of B level sub-pixel causes.In addition, R, the G for showing original data content under highlighted display mode, B level sub-pixel and under highlighted display mode with high brightness carry out R, the G shown, B level sub-pixel area not identical when, suitably can also adjust the transmittance of color filter of corresponding R, G, B level sub-pixel, to guarantee that the display effect of display screen 1 under general display mode can not change, and under highlighted display mode, suppress the generation of serious colour cast situation.Below, by display and control that the pixel layout and control module 2 that describe display screen in accordance with another embodiment of the present invention perform.
Fig. 3 is the schematic diagram of the diagram pixel layout of the display screen of terminal device in accordance with another embodiment of the present invention.
As shown in Figure 3, each R, G, B sub-pixel of display screen all comprises the secondary sub-pixel (the first unit display unit and the second unit display unit) of two corresponding primary colours according to an embodiment of the invention.Particularly, for R sub-pixel, R sub-pixel comprises two R time adjacent level sub-pixels, and for G sub-pixel, G sub-pixel comprises two G time adjacent level sub-pixels, and for B sub-pixel, R sub-pixel comprises two B time adjacent level sub-pixels.
Here, different from the embodiment of Fig. 2, one of two secondary sub-pixels of R (or G or B) (hereinafter referred to first level sub-pixel) are the liquid crystal pixels with TFT drives structure (TFT transistor), and another the secondary sub-pixel (hereinafter referred to second subprime sub-pixel) in two secondary sub-pixels of R (or G or B) is the liquid crystal pixel with driving structure for opening/closing.Here, the liquid crystal pixel with driving switch structure is the liquid crystal pixel that can be in all-transparent and opaque state based on switch controlling signal.Namely, second subprime sub-pixel is when receiving control signal (e.g., high level), its liquid crystal layer becomes all-transparent state, and second subprime sub-pixel is when receiving control signal (e.g., low level), its liquid crystal layer becomes opaque state.Compared with the embodiment of Fig. 2, because second subprime sub-pixel does not need to have TFT drives structure (brightness of gradual change can be provided to export), it only needs the most basic driver structure with liquid crystal pixel, therefore second subprime sub-pixel more easily realizes, and its cost is also lower than the TFT liquid crystal pixel of formed objects.Here, because second subprime sub-pixel only can provide bright or complete black two states entirely, therefore in order to not affect the display of general display mode, picture signal (being equivalent to the high level of control signal) can not be provided as second subprime sub-pixel when general display mode.In this case, the area of second subprime sub-pixel should be less than the area of first level sub-pixel, otherwise can occur comparatively significantly interval under general display mode on display screen 1, causes the granular sensation of display screen 1 heavier.Here, according to one embodiment of present invention, as shown in Figure 3, the area of first level sub-pixel and the area ratio of second subprime sub-pixel can be 3: 1
According to the present embodiment, if control module 2 controls under display screen 1 is in general display mode, then control module 2 is providing the picture signal of the view data with original (normally) to first level sub-pixel in each R (or G or the B) sub-pixel of display screen 1, and does not provide any signal to the second subprime sub-pixel in each R (or G or B) sub-pixel.In this case, according to the display effect of the display screen 1 of the embodiment of the present invention and display screen of the prior art similar.
In addition, under control module 2 is in highlighted display mode based on the detection signal of brightness impression unit 3 or the input control display screen 1 of user, then control module 2 is while providing the picture signal with original (normally) view data to first level sub-pixel in each R (or G or the B) sub-pixel of display screen 1, provides another picture signal to second subprime sub-pixel.Here, another picture signal provided to second subprime sub-pixel is in all-transparent state of switch control signal corresponding to making second subprime sub-pixel, namely another picture signal level with make second subprime sub-pixel be in all-transparent state of switch control signal to mate.
Here, suppose that the backlight illumination of display screen 1 is 1000nit, and the transmittance of R (or G or the B) color filter of R (or G or B) secondary sub-pixel is 10%.In this case, if certain the R sub-pixel in the display screen of prior art is based on picture signal (R127, the transmittance representing R sub-pixel is 50%) when showing, the brightness of its R sub-pixel can be expressed as 1000*50%*10%=50nit.But according to the present embodiment, when display screen 1 is in hi-bright mode, first level sub-pixel in R sub-pixel shows based on picture signal (R127), and second subprime sub-pixel is in all-transparent state.In this case, then the brightness of whole R sub-pixel is (1000*50%*10%*3+1000*100%*10%)/4=62.5nit.Here, due under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, identical with to the process of R sub-pixel to the process of G with B sub-pixel, no longer repeated description is carried out to it here.
Be not difficult to find out from foregoing description, under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, when the brightness of backlight is constant, when display image signals R127, the brightness of R sub-pixel improves 25%.In addition, when the brightness that the picture signal with raw data represents is darker, the effect of luminance raising is more obvious.And G and B sub-pixel also has identical effect.Therefore, under the hi-bright mode of the display screen 1 according to the embodiment of the present invention, display screen 1 can provide obviously higher brightness, and user also can the content of clearly display on browse displays screen 1 in outdoor thus.
Below, by display and control that the pixel layout and control module 2 that describe display screen in accordance with another embodiment of the present invention perform.Fig. 4 is the schematic diagram of the diagram pixel layout of the display screen of terminal device in accordance with another embodiment of the present invention.
