Description
Technical field
The utility model relates to technical field of liquid crystal display, relates in particular to a kind of display panel and display device.
Background technology
Lcd technology has become the mainstream technology in current demonstration field, wherein tft liquid crystal shows that (Thin Film Transistor Liquid Crystal Display, TFT-LCD) product has that volume is little, low in energy consumption, radiationless, the display resolution advantages of higher has been widely used in the modern digital Informationization Equipment.
A senior super dimension switch technology (ADvanced Super Dimension Switch, ADS) be the wide visual angle of plane electric fields core technology, the electric field that the electric field that it produces by gap electrode edge in the same plane and gap electrode layer and plate electrode interlayer produce forms multi-dimensional electric field, make in the liquid crystal cell between gap electrode, all aligned liquid-crystal molecules can both produce rotation directly over the electrode, thereby improved the liquid crystal work efficiency and increased light transmission efficiency.Senior super dimension field switch technology can improve the picture quality of TFT-LCD product, and the TFT-LCD that uses a senior super dimension switch technology has high resolving power, high permeability, low-power consumption, wide visual angle, high aperture, low aberration, without advantages such as water of compaction ripples (push Mura).Fringe field switching (Fringing Field Switching, FFS) technology and plane conversion (In-Plane Switching, IPS) technology is senior super two kinds of tieing up in the switch technology, can improve the technology of LCD image quality, FFS type and IPS type LCD possess the unexistent wide viewing angle of traditional twisted-nematic (Twist Nematic, TN) type LCD.
FFS-LCD and IPS-LCD also are comprised of array base palte, colored filter substrate and the liquid crystal layer that is filled between the two substrates.Different from traditional TN type LCD is, public electrode is not to be formed on the colored filter substrate, but be formed on array base palte on the same with pixel electrode.Take FFS-LCD as example, as shown in Figure 1, traditional FFS-LCD comprises the liquid crystal layer 8 between array base palte and colored filter substrate and two-layer substrate.Wherein be formed with many grid lines 3, data line 4, TFT5, transparent pixels electrode 6, transparent common electrode 7 etc. on the substrate 2 of array base palte, the substrate 12 of colored filter substrate to array base palte is formed with black matrix 9, three primary colours look resistance layer 10 and flatness layer (Over Coat) 11 successively, and the back side of substrate 12 also is formed with back side ITO13.
In such array base palte, array base palte polaroid 1 what see through direction of principal axis and colored filter substrate polaroid 14 is orthogonal through direction of principal axis.When not applying electric field, the major axis of the liquid crystal molecule of liquid crystal layer 8 is parallel to frictional direction and is arranged in liquid crystal cell inside.Because liquid crystal molecule does not rotate, the polarized light that sees through array base palte polaroid 1 does not change through polarization direction after the liquid crystal layer 8, and above-mentioned polarized light can't see through colored filter substrate polaroid 14 again, and liquid crystal display device is shown as black; After applying electric field, the liquid crystal molecule that is parallel to frictional direction deflects, and the polarized light that sees through array base palte polaroid 1 after the deflection changes through polarization direction after the liquid crystal layer 8, partly sees through colored filter substrate polaroid 14.Under the different driving voltages, liquid crystal display has different transmitances, demonstrates different GTGs.
Existing FFS-LCD is in booting moment driving circuit initialization procedure, be formed at array base palte viewing area (drawing the rectangular area AA of fork among Fig. 2) peripheral wiring region (both sides of viewing area among Fig. 2) owing to being arranged in the grid lead 15(of array base palte 2 sides) need apply different voltage, voltage difference between the left and right sides grid lead 15 forms field effect between grid lead 15 at this moment, and induction field produces induced charge 16.Because black matrix layer 9 adopts low-resistance material to make, therefore it adsorbs induced charge 16, and conductive layer is not set on the colored filter substrate 12, and being deceived the induced charge 16 of matrix layer 9 absorption can't derive, and induced charge 16 is by the viewing area diffusive migration of black matrix layer 9 to the centre.Between the substrate 12 of the substrate 2 of array and colored filter, produce stray capacitance like this, formed electric field.The liquid crystal molecule of liquid crystal layer 8 rotates under the driving of this electric field, causes when black picture originally that lighttight zone has light to pass through, and white line appears in screen sides, has reduced display quality, as shown in Figure 2.
