Hold above-mentioned, because each pixel only comprises two sub-pixels in the diagram, these two sub-pixels can provide the first colouring information and the second colouring information respectively, those skilled in the art are known is generally through at least three different colouring informations to produce colour picture, therefore, in the present embodiment except adopting the first above-mentioned colouring information and the second colouring information, additionally use the 3rd colouring information and carry out color compensating to produce colour picture.3rd colouring information provided by least two sub-pixels adjacent with each pixel, or provided by with adjacent at least two sub-pixels on each pixel diagonal line, below will elaborate with Fig. 5.
Fig. 5 is the schematic diagram of the display of another embodiment of the present invention.For convenience of description, the partial pixel of display 500 is only shown in Fig. 5.As shown in Figure 5, pixel 50 comprises to send the sub-pixel 50-1 of blue light B and the sub-pixel 50-2 in order to send red light R, therefore in pixel 50, the sub-pixel sending green light G is lacked, and the colouring information of the green light G that pixel 50 lacks provided in order to provide the sub-pixel of green light G by least two adjacent with pixel 50, such as jointly provide by with sub-pixel 51-2 and sub-pixel 52-1, or jointly provided by sub-pixel 53-2 and sub-pixel 54-1, also can be by sub-pixel 53-2, sub-pixel 54-1, sub-pixel 55-2 and sub-pixel 56-1 provides jointly, to be used for doing color compensating to the colouring information of the green light G that pixel 50 lacks.
Special one carries, and aforesaid first colouring information comprises the first display brightness, the first display brightness with provide the area of the sub-pixel of the first colouring information to be inversely proportional to.Aforesaid second colouring information comprises the second display brightness, the second display brightness with provide the area of the sub-pixel of the second colouring information to be inversely proportional to.Aforesaid 3rd colouring information comprises multiple 3rd display brightness provided by least two sub-pixels, each the 3rd display brightness with provide the area of the sub-pixel of the 3rd display brightness to be inversely proportional to.First colouring information is such as the colouring information showing blue picture, and the second colouring information is such as the colouring information showing red picture, and the 3rd colouring information is such as then the colouring information showing green picture.For example, please jointly with reference to Fig. 3 and Fig. 4, pixel 31 in Fig. 3 is identical with pixel 41 area in Fig. 4, but the pixel in Fig. 3 31 comprises three sub-pixels 31-1,31-2,31-3, and the pixel 41 in Fig. 4 only comprises two sub-pixels 41-1,41-2, therefore in pixel 41, the area of each sub-pixel is each sub-pixel area 3/2nds in pixel 31, if therefore make sub-pixel 31-1 equal with the colouring information that sub-pixel 41-1 produces, then the display brightness 2/3rds of the display brightness needed for sub-pixel 41-1 needed for sub-pixel 31-1.
Hold above-mentioned, please coordinate with reference to Fig. 3 and Fig. 5, because pixel 50 only comprises two sub-pixel 50-1 and sub-pixel 50-2, therefore the display brightness in the middle of pixel 50 needed for each sub-pixel is each sub-pixel 2/3rds in the middle of pixel 31, the display brightness needed for each sub-pixel namely in the middle of pixel 50 can save 1/3rd compared with the display brightness needed for each sub-pixel in the middle of pixel 31, and the present invention utilizes 1/3rd display brightness of saving to carry out color compensating to adjacent pixel.
Next by with the pixel 50 in Fig. 5 and multiple matrix form, color compensating is described.First illustrate, the color compensating mode when showing two-dimensional picture.When as sub-pixel 52-1 and sub-pixel 51-2, the colouring information to the green light G that pixel 50 lacks does color compensating, can represent with matrix A 1 and A2 respectively:
In the middle of matrix A 1 2/3 is represent that the display brightness of sub-pixel 52-1 is any one sub-pixel display brightness 2/3rds in Fig. 3, compare down the display brightness saving 1/3rd, and 1/3rd display brightness of saving can in order to do color compensating to pixel 50, namely matrix A 1 when shown in 1/3.Similarly, matrix A 2 when shown in 2/3 be represent that the display brightness of sub-pixel 51-2 is any one sub-pixel display brightness 2/3rds in Fig. 3, compare down the display brightness saving 1/3rd, / 3rd display brightness of saving are then same in order to do color compensating to pixel 50, namely matrix A 2 when shown in 1/3.According to above-mentioned known, due to sub-pixel 52-1 and sub-pixel 51-2 1/3rd display brightness saved jointly pixel 50 is done to the color compensating of green light G, therefore pixel 50 can obtain in Fig. 3 through color compensating that any one sends sub-pixel 2/3rds display brightness of green light G, but the area due to sub-pixel each in Fig. 5 is each sub-pixel area 3/2nds in Fig. 3, therefore the colouring information obtained still can be equal to the colouring information of each sub-pixel in Fig. 3, thus can compensate the colouring information only having two sub-pixels to lack in a pixel and carry out normal color display.Be explanation that the 3rd colouring information provided by adjacent two sub-pixels does above.
Except the 3rd colouring information that can provide by above-mentioned two sub-pixels (such as sub-pixel 52-1,51-2) adjacent with object pixel (such as pixel 50) does except color compensating to object pixel, the present invention can also do color compensating by with the sub-pixel in adjacent at least two pixels on object pixel diagonal line to object pixel.And special one carry be, due to when showing three-dimensional picture, sub-pixel in four neighbors up and down of object pixel can separately cover by the barrier region of correspondence, therefore under the situation of display three-dimensional picture, just cannot do color compensating by with the sub-pixel in the neighbor of object pixel to object pixel, just must can reach the effect of color compensating by the 3rd colouring information provided with the sub-pixel in adjacent multiple pixels on object pixel diagonal line.Therefore, next by introducing the 3rd colouring information how sub-pixel corresponding in adjacent four pixels provides, color compensating is done to pixel 50, and particularly adjacent on diagonal line four sub-pixels 53-2,54-1,55-2,56-1.It should be noted that, although be to explain with adjacent four sub-pixels 53-2,54-1,55-2,56-1 on pixel 50 diagonal line in the present embodiment, but know those skilled in the art when can understand can also only by with adjacent two sub-pixels on pixel 50 diagonal line to reach the effect of color compensating, therefore following detailed description is only citing, and the present invention is not as limit.
In above-mentioned, when sub-pixel 53-2, sub-pixel 54-1, sub-pixel 55-2 and sub-pixel 56-1 provide the 3rd colouring information to pixel 50 jointly, during the colouring information of the green light G namely providing pixel 50 to lack, can represent with matrix A 3, A4, A5, A6 respectively:
For matrix A 3, it represents that sub-pixel 53-2 does color compensating to pixel 50, central 2/3 is represent that the display brightness of sub-pixel 53-2 is any one sub-pixel display brightness 2/3rds in Fig. 3, compare down the display brightness saving 1/3rd, but do color compensating owing to being through four sub-pixels in the middle of this example, therefore each sub-pixel needs the display brightness provided to be half when only doing color compensating with two sub-pixels, namely 1/6 shown in matrix A 3.For matrix A 4, it represents that sub-pixel 54-1 does color compensating to pixel 50, central 2/3 is represent that the display brightness of sub-pixel 53-2 is any one sub-pixel display brightness 2/3rds in Fig. 3, compare down the display brightness saving 1/3rd, but do color compensating owing to being through four sub-pixels in the middle of this example, therefore each sub-pixel needs the display brightness provided to be half when only doing color compensating with two sub-pixels, namely 1/6 shown in matrix A 4.For matrix A 5, it represents that sub-pixel 55-2 does color compensating to pixel 50, central 2/3 is represent that the display brightness of sub-pixel 55-2 is any one sub-pixel display brightness 2/3rds in Fig. 3, compare down the display brightness saving 1/3rd, but do color compensating owing to being through four sub-pixels in the middle of this example, therefore each sub-pixel needs the display brightness provided to be half when only doing color compensating with two sub-pixels, namely 1/6 shown in matrix A 3.For matrix A 6, it represents that sub-pixel 56-1 does color compensating to pixel 50, central 2/3 is represent that the display brightness of sub-pixel 56-1 is 2/3rds of any one sub-pixel display brightness in Fig. 3, save the display brightness of 1/3rd in comparison, but do color compensating owing to being through four sub-pixels in the middle of this example, therefore each sub-pixel needs the display brightness provided to be half when only doing color compensating with two sub-pixels, namely 1/6 shown in matrix A 3.According to above-mentioned known, due to sub-pixel 53-2, sub-pixel 54-1, the half of 1/3rd saved display brightness is supplied to the color compensating that pixel 50 is green light G by sub-pixel 55-2 and sub-pixel 56-1 separately jointly, therefore pixel 50 can obtain in Fig. 3 through color compensating that any one sends 2/3rds display brightness of the sub-pixel of green light G, but the area due to sub-pixel each in Fig. 5 is 3/2nds of each sub-pixel area in Fig. 3, therefore the colouring information obtained still can be equal to the colouring information of each sub-pixel in Fig. 3, thus can compensate the colouring information only having two sub-pixels to lack in a pixel and carry out normal color display.
In addition, the color offset phenomenon of mode to display display three-dimensional picture that present invention also offers a kind of signal transacting compensates.Please refer to Fig. 1 C, in fig. 1 c, each hatched example areas and each white space contain a pixel separately, and contain three sub-pixels in each pixel, the plurality of sub-pixel be such as send red light R sub-pixel 10-1, in order to send the sub-pixel 10-2 of green light G and the sub-pixel 10-3 in order to send blue light B.The shape of each sub-pixel is long limit with the length of minor face than the rectangle being three to, the coloured light that each oblique line block sends in order to cover respective pixel, the coloured light that each white space sends in order to TEM investigation pixel, the area of each hatched example areas and each blank block is the area being equal to each pixel, wherein, the display area of each sub-pixel and the product of luminosity equal, therefore when display produces color offset phenomenon, namely luminosity by adjustment corresponding sub-pixel can eliminate color offset phenomenon, to explain further below.When fringe field effects occurs, the area of hatched example areas can become large and make to be such as that the subregion on the right in left-hand component region and sub-pixel 10-3 in sub-pixel 10-1 is covered, therefore, the red light R that sends respectively of sub-pixel 10-1 and sub-pixel 10-3 and blue light B can be become large hatched example areas to cover and amount of light is reduced be such as X%.Sub-pixel 10-2 covered, so its amount of light can't be subject to the impact of fringe field effects and reduce owing to can't be subject to becoming large hatched example areas.Therefore, if the amount of light of the green light G sent by sub-pixel 10-2 also reduces X% accordingly, the amount of light of each sub-pixel just can be made equal and avoid the generation of color offset phenomenon.
In sum, the present invention does corresponding design by sub-pixel and barrier region area and penetration region area and reaches the effect improving colour cast, such as when a pixel has three sub-pixels or only has two sub-pixels when a pixel, be the area being equal to adjacent two sub-pixels by the area design of barrier region and penetration region, change can make under fringe field effects, make the amount of light of each sub-pixel equal thus, and then improves color offset phenomenon.And when a pixel only comprises two sub-pixels, the present invention can obtain the colouring information identical with the pixel comprising three sub-pixels through the inverse relation between sub-pixel area and display brightness, and relation carries out color compensating and the pixel making only to have two sub-pixels still can normal Show Color information whereby.Even if the area of barrier region and penetration region is equal to the area of three adjacent subpixels, the present invention can also through the mode of signal transacting, the amount of light of the sub-pixel do not affected by fringe field effects is done corresponding adjustment, make the amount of light of each sub-pixel equal, thus can reach the effect eliminating color offset phenomenon equally.
