in step S1, a liquid crystal display panel 10 is provided. The liquid crystal display panel 10 is a flat plate, and the liquid crystal display panel 10 is different from a curved liquid crystal display screen in that the liquid crystal display panel 10 is not bent and a metal wire grid polarizer is not installed. The liquid crystal display panel 10 includes a first substrate, a second substrate, and a liquid crystal cell sandwiched between the first substrate and the second substrate.
Step S2, providing a polarizer, where the polarizer includes a first polarization region 23 and a second polarization region 24 connected to the first polarization region. The first and second light polarizing regions 24 are selected according to the defect position of the common liquid crystal display panel 10 during the bending process.

The first wire grid 202 and the second wire grid 203 can be collectively referred to as a wire grid. The grid pitch P of all the wire grids on the metal wire grid polarizer 20 is the same, the grid pitch P is the sum of the width of one wire grid and the pitch of two adjacent wire grids, and the height H of each wire grid relative to the surface of the metal wire grid polarizer 20 is the same. The first polarization region 23 has a wire grid duty cycle that is smaller than a wire grid duty cycle of the second polarization region 24, the wire grid duty cycle being a ratio of a width of one wire grid to a distance between two adjacent wire grids 22.
In this section, the width W1 of the first metal wire grid 202 of the first polarization area 23 of the metal wire grid polarizer 20, the distance between two adjacent first metal wire grids 202 is W2, and the duty ratio of the wire grid located in the first polarization area 23 is W1/W2; the width W3 of the second metal wire grid 203 of the second polarization area 24, the distance between two adjacent second metal wire grids 203 is W4, and the duty ratio of the wire grid in the second polarization area is W3/W4; under the condition that the height H and the grid pitch P of the wire grid are constant, W1/W2 is smaller than W3/W4, W1 and W2 are invariable, the duty ratio of the wire grid on the metal wire grid polarizer 20 is selected, and the width and the pitch of the wire grid are further set according to the analog numerical value range of brightness, penetration rate and the like obtained by performing brightness test on a curved liquid crystal display panel with uneven brightness after being bent.
Step S4, mounting the metal wire grid polarizer 20 on the liquid crystal display panel 10;

Specifically, the first display region includes first sub-display regions a1 located at two opposite sides of the second display region B, and the duty ratios of the two first sub-display regions a1 are the same. The two first sub-display areas a1 are located at opposite sides of the liquid crystal display panel 10. In this embodiment, two opposite sides of the curved liquid crystal display panel are bent toward the middle region, the radian of the first display region a1 is greater than the radian of the second display region B, and during the bending process, the duty ratio of the first polarization region 23 of the wire grid polarizer 20 is different from the duty ratio of the second polarization region, so that the brightness of the first display region can be compensated. Specifically, the step of bending the part of the liquid crystal display panel with the metal wire grid polarizer to form the liquid crystal display panel includes bending the opposite two side parts of the liquid crystal display panel with the middle area of the liquid crystal display panel 10 as a bending reference. The middle area is the second display area, and the two side parts are the first display areas.
Of course, according to the requirement of the curved shape of the curved liquid crystal display, other parts can be bent, for example, one end of the curved liquid crystal display is bent, and one part of the liquid crystal display panel is required to be used as a bending reference to bend the other part of the liquid crystal display panel.
In the method for manufacturing the curved-surface liquid crystal display screen, the metal wire grid polaroid is manufactured into the areas with different duty ratios, so that the characteristics of different penetration rates can be realized; the areas with different duty ratios are opposite to the parts of the liquid crystal display screen which are bent and easily generate brightness defects, so that the curved liquid crystal display screen formed after the liquid crystal display screen is bent has uniform display brightness.
Referring to fig. 4, the present invention provides a curved liquid crystal display panel, which is manufactured by the above method, and includes a liquid crystal display panel 10 and a wire grid polarizer 20 laminated on the liquid crystal display panel 10. The liquid crystal display panel 10 includes a first substrate, a second substrate disposed opposite to the first substrate, and a liquid crystal cell located between the first substrate and the second substrate, where the first substrate is a color film substrate, and the second substrate is an array substrate. The metal wire grid polarizer 20 is laminated on the first substrate, and may be understood as being laminated on the first substrate on the side facing the liquid crystal layer, or may be laminated on the outer surface of the glass substrate of the first substrate. In this embodiment, the metal wire grid polarizer 20 is laminated on the outer surface of the glass substrate of the first substrate. The liquid crystal display panel 10 further comprises a display surface 101, wherein the display surface 101 comprises a first display area and a second display area B connected with the first display area, and the radian of the first display area is greater than that of the second display area B; it is understood that the liquid crystal display panel includes the second display region B to which the first display region is connected. The first display area may include two portions or may be a portion, and this embodiment refers to two portions located in the second display area.
A plurality of wire grids (not shown) are disposed on a surface 201 of the metal wire grid polarizer 20 at intervals in parallel, and referring to fig. 3, the metal wire grid polarizer 20 includes a first polarization region 23 corresponding to the first display region and a second polarization region 24 corresponding to the second display region B, a wire grid duty ratio of the first polarization region 23 is smaller than a wire grid duty ratio of the second polarization region 24, wherein the wire grid duty ratio is a ratio of a width of one wire grid to a distance between two adjacent wire grids. The grid pitches P of a plurality of wire grids on the metal wire grid polarizer 20 are the same, the grid pitch P is the sum of the width of one wire grid and the pitch of two adjacent wire grids, and the height H of each wire grid relative to the surface of the metal wire grid polarizer 20 is the same. The height H and pitch P of the wire grid are quantitative. The transmittance of the first polarizing region 23 of the metal wire grid polarizer 20 is different from that of the second polarizing region 24.
Because the radian of the first display area a1 is greater than the radian of the second display area B, that is, the curvature of the first display area a is greater, and in the process of bending the liquid crystal display panel, the portion serving as the bending area is the main deformation area, and the curvature of the main deformation area is greater than the curvature of the reference portion, because the curved liquid crystal display screen is bent to make a curved screen after the liquid crystal display screen is made into a box, the brightness distribution of the LCD liquid crystal display screen is uneven after the LCD liquid crystal display screen is bent into a curved surface, so that the brightness difference is caused, the duty ratio of the wire grid in the local area of the metal polarizer 20 is changed, and the duty ratio of the first polarization area 23 of the wire grid polarizer 20 is different from the duty ratio of the second polarization area, so that the brightness of the first display area can be compensated. Set up the metal wire grating polaroid into the polarizing zone that has the duty cycle difference in advance in this application, different penetration rates of regional formation of difference promptly, correspond the different luminance region of liquid crystal display panel to compensate the difference of liquid crystal display panel luminance homogeneity, solve LCD liquid crystal display because buckle the uneven problem of demonstration that causes behind the closed liquid crystal. Meanwhile, if the metal wire grid polarizer is arranged inside the display screen, the influence of inconsistent deformation caused by increasing the thickness of the glass substrate on the glass substrate can be reduced when the metal wire grid polarizer is not directly attached to the glass substrate, and the problem that the LCD cannot be subjected to curved surface display with larger curvature is solved.
Referring to fig. 5, in another embodiment, a curved liquid crystal display panel is formed by bending a curved liquid crystal panel on one side of the curved liquid crystal display panel, so that the duty ratio of the wire grid in the polarizer region of the metal wire grid corresponding to the bent portion is smaller than the duty ratio of the wire grid corresponding to the reference portion. Specifically, the region a1 is bent based on the region B in fig. 5, so that the duty ratio of the first polarization region of the metal wire grid polarization change 20 corresponding to the region a1 can adjust the brightness effect of the region a1 due to the bending. In other embodiments, not shown, the display surface further includes a third display region connected between the first display region and the second display region, and the metal wire grid polarizer includes a third polarization region corresponding to the third display region, and a duty ratio of the third polarization region is smaller than a duty ratio of the second polarization region. Specifically, the liquid crystal display panel is bent in comparison with the second bending region by taking the third display region as the bending region, and the duty ratio of the third light polarizing region is smaller than that of the second light polarizing region, so that the brightness uniformity of the second display region, the third display region and the first display region is adjusted.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
