[embodiment]
For making above-mentioned purpose of the present invention, characteristic and advantage more obviously understandable, hereinafter is special lifts preferred embodiment of the present invention, and conjunction with figs., elaborates as follows.Moreover, the direction term that the present invention mentioned, for example " on ", D score, " preceding ", " back ", " left side ", " right side ", " interior ", " outward ", " side " etc., only be direction with reference to annexed drawings.Therefore, the direction term of use is in order to explanation and understands the present invention, but not in order to restriction the present invention.
Please refer to shown in Figure 3ly, the pixel cell that Fig. 3 discloses the LCD of the present invention's one preferred embodiment distributes.A kind of LCD comprises a viewing area 10 and a plurality of pixel cells 11, and said pixel cell 11 is to be arranged in the said viewing area 10 with the two-dimensional array mode.Further with reference to shown in Figure 4; Fig. 4 discloses the composition structure of said pixel cell 11; Each said pixel cell 11 is made up of a plurality of sub-pixel unit side by side; A plurality of sub-pixel unit described in the present embodiment are respectively one first sub-pixel unit 110, one second sub-pixel unit 111 and one the 3rd sub-pixel unit 112, to control the demonstration of Red Green Blue respectively.Each said sub-pixel unit is a square block, for example is rectangle block or square block etc.Said square block is to be distinguished into a clear zone piece 100A and a dark space piece 100B along an oblique line 100, and can be that the direction according to LCD alignment is different make differentiation for said clear zone piece 100A and said dark space piece 100B.Said oblique line 100 can be a diagonal line of said square block, makes that said clear zone piece 100A and said dark space piece 100B are all triangular in shape.
Moreover the oblique line 100 of distinguishing said clear zone piece 100A and said dark space piece 100B on each said sub-pixel unit and the oblique line of adjacent subpixels unit 100 are non-to be parallel.Be with; If the diagonal line that is said sub-pixel unit with said oblique line 100 is an example; Like Fig. 3 and shown in Figure 4; The dark space piece 100B that can find out the sub-pixel unit that the clear zone piece 100A of each said sub-pixel unit is adjacent all is to be that axis of symmetry is mutual correspondence (corresponding to each other) or contraposition (align with each other) each other with a transverse axis or a Z-axis, and it is symmetrical also can being called.For example from said first sub-pixel unit 110, the clear zone piece 100A of said first sub-pixel unit 110 is corresponding each other with the dark space piece 100B of said second sub-pixel unit 111.If from said second sub-pixel unit 111, the clear zone piece 100A of the said second sub-pixel unit 111 not only dark space piece 100B with said first sub-pixel unit 110 is corresponding each other, also the dark space piece 100B of while and the 3rd sub-pixel unit 112.
Further with reference to shown in Figure 5; When the oblique hachure of said liquid crystal display displays one; Can find out and show that black more can not receive the dark space 110B influence of neighborhood pixels unit 11 and the sensation that visually becomes big, the sawtooth effect of also just having subdued said oblique hachure are arranged with the pixel cell 11 ' that constitutes said oblique hachure.
As stated; Though can reach the purpose of improving the visual angle phenomenon with the horizontal resection sub-pixel unit compared to the available liquid crystal display; But in increase along with the liquid crystal panel size; This existing structure is also because of the mode of horizontal resection, and shortcoming such as the sawtooth phenomenon is more obvious when causing showing oblique hachure, the LCD of the present invention of Fig. 3 and pixel cell thereof cut into said clear zone piece 110A and said dark space piece 110B through each sub-pixel unit at said pixel cell 11 with oblique line; It can effectively subdue described crenellated phenomena really, and then promotes the image quality that the large scale liquid crystal panel shows.
The present invention is described by above-mentioned related embodiment, yet the foregoing description is merely the example of embodiment of the present invention.Must be pointed out that disclosed embodiment does not limit scope of the present invention.On the contrary, being contained in the spirit of claims and the modification and impartial setting of scope includes in scope of the present invention.
