Description

Dot structure

Technical field

The present invention relates to a kind of dot structure, and particularly relate to a kind of dot structure that improves dark line phenomenon.

Background technology

Existing market for liquid crystal display panel of thin film transistor (TFT liquid crystal display panel) all towards height contrast (contrast ratio), without future developments such as gray inversion (gray scale inversion), high brightness (brightness), high color saturation (color saturation), rapid reaction (response) and wide viewing angles (viewing angle).Common wide viewing angle technology comprises that stable twisted nematic liquid crystal (TN) adds view film (wide viewing film), copline suitching type (In-Plane Switching at present, IPS) display panels, a limit suitching type (Fringe Field Switching, FFS) display panels and multidomain vertical alignment type (Multi-domain Vertical Alignment, MVA) display panels.

Taking limit, suitching type (Fringe Field Switching, a FFS) display panels is as example, and it has the advantageous properties such as wide viewing angle (wide viewing angle) and low colour cast (color shift).In existing FFS display panels, be to produce horizontal component of electric field with the pressure reduction up and down of pixel electrode and this two-layer electrode of common electrode, to drive the rotation of liquid crystal molecule.

Fig. 1 is the schematic diagram of the dot structure of existing FFS display panels.Fig. 2 is the photo schematic diagram of the dark line phenomenon of the display panels of Fig. 1.Referring to Fig. 1 and Fig. 2, dot structure 10 has lower electrode layer 120 and upper electrode layer 140, and upper electrode layer 140 is made up of many branch electrodes 142,144.As shown in Figure 1, the branch electrodes 142 of upper electrode layer 140 is different from the configuration direction of branch electrodes 144, and can form respectively region (domain) R and region R '.Because the region R of upper electrode layer 140 has different electric force lines distribution from region R ', if it is too wide to be positioned at the branch electrodes 142,144 of intersection K of region R and region R ', easily make the toppling direction indefinite (disclination) corresponding to the liquid crystal molecule of intersection K, cause existing FFS display panels to produce unexpected dark line or light leak in the time showing, further make display panels light leakage phenomena occur or briliancy is low in the time showing bright state picture when dark state picture showing.Therefore, how to improve display brightness and the contrast of FFS display panels, make it have better display quality, real is one of developer institute goal to be achieved.
