The application's concrete principle analysis following (embodiment arranging with the application's arc-shaped side along continuous straight runs explains orally):
Traditional panel, colored filter is produced on prebasal plate, and the colored filter intersection of different colours need to form light non-transmittable layers, JiBM covers in district the region of blend of colors, can significantly reduce the interference that between liquid crystal display pixel, colour mixture produces like this, thereby present more stable and affect clearly quality; Thin film transistor (TFT) is produced on metacoxal plate, between prebasal plate and metacoxal plate, there is certain gap, liquid crystal molecule is filled among gap, by external drive control panel output voltage and signal, controls the switch of thin film transistor (TFT), thereby realize the control discharging and recharging of pixel.
Curved surface display technique need be carried out certain angle bending by display panel, and certain angle skew can occur visual range when crooked rear real visual angle and bending, on showing, presents colour cast problem.
Utilizing traditional panel to make curved surface shows and liquid crystal panel need to be carried out to bending with certain curvature, because its prebasal plate is identical with metacoxal plate display area size, so the arc length of the viewing area arc-shaped side of the display panel prebasal plate after bending and the arc-shaped side arc length of metacoxal plate viewing area equate.
Below in conjunction with Fig. 1 with COT(Color Filter on TFT, that is: colored filter and thin film transistor (TFT) coexist on prebasal plate or metacoxal plate) product of panel and normal liquid crystal panel (CF and TFT divide out on 2 sheet glass substrates) is example, carry out theoretical analysis: prebasal plate viewing area arc-shaped side arc length is ∏ * a1*R1/180, the central angle of the arc-shaped side that wherein a1 is prebasal plate, R1 is the radius of the arc-shaped side of prebasal plate, making prebasal plate viewing area arc-shaped side arc length is ∏ * a1*R1/180, metacoxal plate viewing area arc-shaped side arc length is ∏ * a2*(R1+n)/180, wherein n is the distance of front and back panel viewing area, a2 is the central angle of the arc-shaped side of metacoxal plate,
According to above-mentioned formula, calculate, under the equal condition of arc length, the gap of prebasal plate and metacoxal plate is added and considered, slightly large in the outer field panel radius of bending, after bending, in outer field cambered surface loss Shi center angle, on display area and visual angle, lose.For the panel after bending, central angle at the arc-shaped side of prebasal plate and horizontal direction viewing area on metacoxal plate after panel bending is different, and the central angle of the arc-shaped side on prebasal plate is a1, and the central angle of the arc-shaped side on metacoxal plate is a2, vertical-direction length does not change, and a2 is less than a1.If in like manner prebasal plate and metacoxal plate are carried out to bending in vertical direction, vertical direction prebasal plate is different with the central angle of viewing area arc-shaped side after metacoxal plate bending, and cross-directional length is constant.
The method that the present invention takes is, the central angle of the arc-shaped side arc length of the arc-shaped side arc length of the viewing area of metacoxal plate and prebasal plate viewing area is designed to identically in its processing procedure, makes the arc length of metacoxal plate be greater than the arc length of prebasal plate;
That is: as shown in Figure 2, display panel prebasal plate and the viewing area of metacoxal plate are designed to arc length not identical, make both on concentric circles, identical (being a) of central angle of the arc-shaped side of the viewing area of metacoxal plate and the arc-shaped side of prebasal plate viewing area, so that the arc length of metacoxal plate is greater than the arc length of prebasal plate, the picture colour cast problem of viewing area edge while solving curved surface demonstration, does curved surface demonstration more to meet panel.
Take UD(Ultra Definition below) panel describes as example:
Panel CF(Color Filter) thickness is about 6.4 μ m, Cell Gap(thickness of liquid crystal layer) value is about 4 μ m, the spacing of prebasal plate and metacoxal plate is about 10.4 μ m, can calculate thus when central angle is 12 °, after metacoxal plate has and relatively inside contracts, the arc length of prebasal plate and metacoxal plate is poor is Δ l=∏ * a*n/180, bring above-mentioned numerical value into and obtain Δ l=0.0022mm, for UD panel, Pixel is of a size of 0.372mm, Sub-Pixel is of a size of the Pixel size of 0.124mm(1/3rd), (Δ l/0.124mm) * 100% ≈ 1.8%, consider blue accounting 10% in brightness, green accounting 60%, make blue colour cast reach (1.8*0.6)/(1.8*0.6+98.2*0.1)=10%.If radius-of-curvature is less, bending is larger, such as crooked 12 degree, reaches 20% colour cast when central angle is 24 °.
By the arc length design of prebasal plate and metacoxal plate on concentric circles and arc length different, metacoxal plate is increased to 0.0022mm with respect to the arc length of prebasal plate, to metacoxal plate is compensated, colour cast problem is solved; Now, the arc length of prebasal plate and metacoxal plate is poor is Δ l=∏ * a*n/180, bring above-mentioned numerical value into and obtain Δ l=0.0022mm-0.0022mm=0, for UD panel, Pixel is of a size of 0.372mm, and Sub-Pixel is of a size of 0.124mm, (Δ l/0.124mm) * 100% ≈ 0%, consider blue accounting 10% in brightness, green accounting 60%, makes blue colour cast reach (0*0.6)/(0*0.6+98.2*0.1)=0%.Thereby the colour cast problem causing because of panel bending will have been solved.
