Embodiment
For making object of the present invention, technical scheme and advantage clearer, clear and definite, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The invention provides a kind of color filter film display unit, for the array structure of color filter film, the invention provides a kind of color filter film display unit being formed by three primary colours red, green, blue and the 4th kind of color except three primary colours.As shown in Figure 1 to Figure 3, this color filter film display unit comprises two pixels across unit and two the longitudinal pixel cells that are 2 * 2 matrixes arrangements, and every ranks are all arranged a pixels across unit and a longitudinal pixel cell; Pixels across unit and longitudinally pixel cell include two sub-pixels, and as shown in Figure 1, this sub-pixel 44 is rectangular shape to the structure of sub-pixel, and preferably adopting length breadth ratio is the rectangle of 2:1, also can adopt the rectangular shape of square or other ratios.Fig. 2 shows the planform of pixels across unit 41 and longitudinal pixel cell 42, wherein, pixels across unit 41 comprises two kinds of color sub-pixels of red R, green G that arrange left and right, two sub-pixels 44 that arrange left and right, the left and right arrangement architecture here also can adopt the green G in the left side, the structure of the right red R sub-pixel; Longitudinally pixel cell 42 comprises the 4th kind of color X and the blue B sub-pixel except three primary colors being arranged above and below, two sub-pixels 44 that are arranged above and below, in like manner, longitudinally pixel cell 42 also can replace with the blue B that is arranged above and below and the structure of the 4th kind of color X sub-pixel except three primary colors; Because sub-pixel is the form that arrange left and right, therefore be referred to as pixels across unit, sub-pixel is the form being arranged above and below, thus be referred to as longitudinal pixel cell, and forms pixels across unit 41 or longitudinally the area of pixel cell 42 is equal by two sub-pixels 44.Fig. 3 shows the structure of color filter film display unit 40, two pixels across unit and two longitudinal pixel cells are formed to 2 * 2 matrix form, each row and column are all arranged as a horizontal display unit 41 and a longitudinal display unit 42, and two horizontal display units 41 and two longitudinal display units 42 are oblique 45 ° of cross modals formation color filter film display unit.
In above-mentioned color filter film display cell structure, the sub-pixel 44 of pixels across unit 41 is long limit vertical direction layout, and longitudinally the sub-pixel 44 of pixel cell 42 is that long limit horizontal direction is arranged.
In above-mentioned color filter film display cell structure, the 4th kind of color preferably adopts Transparent color, and so-called Transparent color refers to that, on the position of this sub-pixel, color filter film is not coated with any color, thereby is referred to as Transparent color.Transparent color sub-pixel can increase transmitance backlight when concrete application, and then can reduce power consumption; Certainly, the 4th kind of color can also adopt cyan or other random colors except three primary colors and Transparent color to realize, and can increase demonstration colour gamut.
The present invention also provides a kind of color filter film array of display cells structure, the matrix array that this array structure adopts above-mentioned color filter film display unit 40 to form, its structure as shown in Figure 4, Fig. 4 shows the structural representation of color filter film array of display cells structure the first embodiment, this array structure is arranged in color filter film 50 surfaces, by color filter film display unit 40, form matrix form, wherein the 4th kind of color adopted Transparent color T to realize.Adopt the color filter film of this array of display cells structure can make identical sub-pixel in the horizontal direction with vertical direction on sampling interval keep in balance, be adjacent transverse pixel cell in the horizontal direction with vertical direction on equal longitudinal pixel cells in one, interval, adjacent longitudinal pixel cell in the horizontal direction with vertical direction on also pixels across unit, one, interval all, and, as shown in Figure 5, each pixels across unit, longitudinally pixel cell is at 45 °, in 135 ° of directions, be all arranged in a linear, in color filter film display unit 40, the center of pixels across unit or longitudinal pixel cell is printing opacity center 45, as example, in Fig. 5, only show the printing opacity center 45 of pixels across unit, longitudinally the printing opacity center of pixel cell is identical with pixels across unit, scheme not shown.Each printing opacity center 45 form that is arranged in a linear in level, vertical and 45 °, 135 ° directions.As shown in Figure 6, the pixels across unit that each is adjacent or the longitudinally pixel cell spacing distance in 45 ° or 135 ° of directions is greater than a half-distance at horizontal direction interval, i.e. distance J1 > J2 shown in figure, such Structure Decreasing the impact of sampling process intermediate frequency spectrum aliasing, when the color filter film 50 with this structure is specifically applied in LCDs, can further improve the resolution of display screen.
The present invention also provides a kind of color filter film 50, and this color filter film adopts above-mentioned color filter film array of display cells structure, does not repeat herein.
Fig. 7 also shows the second embodiment of color filter membrane array structure, in this color filter membrane array structure, different from the first embodiment is, the 4th kind of color replaced with to other colors X except three primary colors RGB, such as, the colors such as white, cyan, can realize the effect of above-described embodiment too.
Color filter film provided by the invention, color filter membrane array structure is a kind of four primary colours pixel display unit structures, this structure is evenly distributed four primary color sub-pixels, be included in level, vertical direction and 45 °, sampling interval in 135 ° of directions is balanced, when this color filter film is applied in LCDs, because the sampling rate in horizontal and vertical direction is higher than 45 °, sampling rate in 135 ° of directions, contribute to LCDs to improve resolution, when the 4th kind of color in four primary colours adopts Transparent color sub-pixel, can increase transmitance backlight, further can reduce the power consumption of backlight module, if adopt cyan or other colors, can also improve the demonstration colour gamut of this color filter film LCDs of application, make the color showing more enrich nature.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
