Description
Technical field
The present invention is about a kind of liquid crystal display panel pixel structure, especially a kind of low colour cast (colorshift) liquid crystal display panel pixel structure.
Background technology
Please refer to shown in Figure 1ly, is the diagrammatic cross-section of a typical display panels.As shown in FIG., this display panels has a upper substrate 120, an infrabasal plate 220 and a liquid crystal layer 300 and constitutes.Wherein, the lower surface of upper substrate 120 is manufactured with a chromatic filter layer (color filter) 140, community electrode layer 160 and one first both alignment layers 180 in regular turn.And be manufactured with a pixel electrode layer 260 and one second both alignment layers 280 in regular turn at the upper surface of infrabasal plate 220.Liquid crystal layer 300 clampings are between first both alignment layers 180 and second both alignment layers 280.Pixel electrode layer 260 is to produce driving electric field to turn to order about liquid crystal molecule in liquid crystal layer 300 with the potential difference (PD) of common electrode layer 160, and then the angle between change liquid crystal molecule and light, adjust 300 pairs of the liquid crystal layers bit phase delay amount (retardation) that light provided.
And as shown in Figure 1, light L1 upwards penetrates along the direction (being the normal direction of upper substrate 120) of vertical upper substrate 120, and light L2 and light L1 accompany the visual angle (viewing angle) of θ degree.Liquid crystal molecule (representing liquid crystal molecule with ellipse among the figure) is obviously different with the angle of light L1 and light L2, and makes light L1 and L2 in the process that penetrates liquid crystal layer 300, produces different positions to carryover effects.And then cause leaving the light L1 of upper substrate 120 and the intensity of L2 has significant difference, just make the brightness of the picture at different visual angles place produce evident difference.And the difference of this brightness often makes picture produce the phenomenon of colour cast (color shift) again.
In order to further specify this color offset phenomenon, Fig. 2 shows a representative vertical orientation, and (verticalaligned, VA) LCD is at an ancient woman's ornament Maqu at different visual angles θ place line (gamma curve).Transverse axis representative color exponent number (bit number) among the figure, and the longitudinal axis is represented light transmittance (opticaltransmission).And corresponding to view angle theta among the figure is that 0 °, 15 °, 30 °, the 45 ° light transmittances with the maximum color range number (being that the color range number is 255) of 60 ° an ancient woman's ornament Maqu line all are set at 1.What therefore, these an ancient woman's ornament Maqu lines were showed is the relative brightness of the picture of different color range numbers with respect to the picture of maximum color range number.
Generally speaking, an ancient woman's ornament Maqu line that corresponds to 0 ° at visual angle is a desirable an ancient woman's ornament Maqu line, that is to say, the picture that is provided according to this an ancient woman's ornament Maqu line has best real colour.And by can finding among the figure that an ancient woman's ornament Maqu line that corresponds to different visual angles is separated from each other, and along with the increase at visual angle, corresponding an ancient woman's ornament Maqu line is also more and more away from an ancient woman's ornament Maqu line at 0 ° at visual angle.Hence one can see that, and the picture of observing in place with great visual angle will produce tangible color offset phenomenon and influences the authenticity of picture color.
So the separation that how to improve an ancient woman's ornament Maqu line of different visual angles produces colour cast to prevent picture, will be to the development of LCD, the especially raising of visible angle produces earthshaking influence.
Summary of the invention
Fundamental purpose of the present invention is for conventional liquid crystal, at the color offset phenomenon that picture occurred with great visual angle, proposes the method that solves.
The invention provides a kind of liquid crystal display panel pixel structure, it comprises a upper substrate, an infrabasal plate, a layer of liquid crystal molecule and community electrode layer at least.Wherein, the layer of liquid crystal molecule clamping is between upper and lower base plate.Common electrode layer is made in the lower surface of upper substrate, and has at least one separation structure common electrode layer is divided into a plurality of blocks.In these a plurality of blocks, comprise one first district and one second district at least, and this first district and second district are connected with one first voltage quasi position and one second voltage quasi position respectively.
The present invention simultaneously also provides a kind of method of improving color cast of liquid crystal display, it is characterized in that adjusting the common voltage of input LCD upper substrate, make each picture (frame) on the sequential all to the common voltage of different voltage quasi positions more than two should be arranged.
