Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly relate to a kind of display panel and display device.
Background technology
Lcd technology has become the mainstream technology in current display field, wherein tft liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) product has that volume is little, low in energy consumption, radiationless, display resolution advantages of higher has been widely used in modern digital Informationization Equipment.
Senior super dimension field switch technology (ADvanced Super Dimension Switch, ADS) be plane electric fields wide viewing angle core technology, the electric field that its electric field produced by gap electrode edge in same plane and gap electrode layer and plate electrode interlayer are produced forms multi-dimensional electric field, make in liquid crystal cell that between gap electrode, directly over electrode, all aligned liquid-crystal molecules can both produce rotation, thus improve liquid crystal work efficiency and increase light transmission efficiency.Senior super dimension field switch technology can improve the picture quality of TFT-LCD product, the TFT-LCD applying senior super dimension field switch technology have high resolving power, high permeability, low-power consumption, wide viewing angle, high aperture, low aberration, without advantages such as water of compaction ripples (push Mura).ADS-LCD is made up of array base palte, colored filter substrate and the liquid crystal layer be filled between two substrates.With traditional TN type LCD unlike, public electrode is not formed on colored filter substrate, but equally with pixel electrode is formed on array base palte.For ADS-LCD, as shown in Figure 1, traditional ADS-LCD comprises the liquid crystal layer 8 between array base palte and colored filter substrate and two-layer substrate.The substrate 2 of wherein array base palte is formed with many grid lines 3, data line 4, TFT5, transparent pixels electrode 6, transparent common electrode 7 etc., substrate 12 to the array base palte of colored filter substrate is formed with black matrix 9, three primary colours color blocking layer 10 and flatness layer (Over Coat) 11 successively, and the back side of substrate 12 is also formed with back side ITO13.
In such array base palte, array base palte polaroid 1 be orthogonal through direction of principal axis and colored filter substrate polaroid 14 through direction of principal axis.When not applying electric field, the longer axis parallel of the liquid crystal molecule of liquid crystal layer 8 is arranged in liquid crystal cell inside in frictional direction.Because liquid crystal molecule does not rotate, the polarized light through array base palte polaroid 1 does not change polarization direction after liquid crystal layer 8, and above-mentioned polarized light cannot again through colored filter substrate polaroid 14, and liquid crystal display device is shown as black; After applying electric field, the liquid crystal molecule being parallel to frictional direction deflects, and changes polarization direction, partly transmit colored filter substrate polaroid 14 after deflection through the polarized light of array base palte polaroid 1 after liquid crystal layer 8.Under different driving voltages, liquid crystal display has different transmitances, demonstrates different GTGs.
Existing FFS-LCD is in booting moment driving circuit initialization procedure, because the grid lead 15(being arranged in array base palte 2 side is formed at array base palte viewing area (in Fig. 2 draw fork rectangular area AA) the peripheral wiring region both sides of viewing area (in the Fig. 2)) different voltage need be applied with, voltage difference now between left and right sides grid lead 15 forms field effect between grid lead 15, and induction field produces induced charge 16.Because black matrix layer 9 adopts low-resistance material to make, therefore its absorption induced charge 16, and colored filter substrate 12 is not arranged conductive layer, cannot be derived by the induced charge 16 that black matrix layer 9 is adsorbed, induced charge 16 is by the viewing area diffusive migration of black matrix layer 9 to centre.Between the substrate 2 and the substrate 12 of colored filter of array, create stray capacitance like this, form electric field.The liquid crystal molecule of liquid crystal layer 8 rotates under the driving of this electric field, and cause the lighttight region of script when black picture to have light to pass through, white line appears in screen sides, reduces display quality, as shown in Figure 2.
