In this embodiment, the curved display section 200 is formed of a plurality of continuous curved surfaces, and includes at least a first curved surface having a first curvature and a second curved surface having a second curvature, wherein the first curvature is greater than the second curvature. In response, the liquid crystal molecules 2301 positioned at the first curvature position have a larger deflection angle than the liquid crystal molecules 2301 positioned at the second curvature position. The deflection angle of the liquid crystal molecules 2301 at different curvature positions can be controlled by applying different driving voltages to the liquid crystal molecules 2301 at different curvature positions.
In this embodiment, the deflection angles of the liquid crystal molecules 2301 at different curvatures are controlled to be different, so as to adjust the light rays with different polarization angles, so as to compensate the problem of light ray divergence or convergence caused by the curved structure.
In the display panel of the present application, the display layer 300 includes a plurality of sub-pixels 301, and each of the light condensation units 2310 corresponds to one of the sub-pixels 301.
In this embodiment, referring to fig. 6, the display layer 300 includes a plurality of sub-pixels 301 distributed in an array, for example, the sub-pixels 301 may be red sub-pixels, green sub-pixels, and blue sub-pixels, where each light condensing unit 2310 corresponds to one of the sub-pixels 301.
In this embodiment, by associating each sub-pixel 301 with each condensing unit 2310, the deflection angle of the light emitted by each sub-pixel 301 can be precisely controlled, so as to adjust the emergent light of each sub-pixel 301, and improve the light divergence and convergence of the curved display portion 200.
In the display panel of the present application, the dimming layer 210 extends from the curved display part 200 to the flat display part 100 and covers the flat display part 100.
In this embodiment, the dimming layer 210 continuously covers the entire display surface of the display panel, that is, the dimming layer 210 covers both the flat display portion 100 and the curved display portion 200. For the curved display section 200, referring to fig. 4B, the first electrode 2110 and the second electrode 2120 can control the deflection of the liquid crystal molecules 2301, thereby forming a lens structure, and improving the problem of light divergence or convergence of the curved display section 200. In the flat display 100, referring to fig. 4A, the first electrode 2110 and the second electrode 2120 may not be applied with a driving voltage, so that the liquid crystal molecules 2301 in the flat display 100 are not deflected and the light emission angle is not affected. The first substrate 2100, the liquid crystal layer 2300, and the second substrate 2200 constitute a line bias layer.
In some embodiments, referring to fig. 5, the light modulating layer 210 in the flat display portion 100 is slightly different from the light modulating layer 210 in the curved display portion 200, i.e. the first electrode 2110 and the second electrode 2120 are not disposed inside the light modulating layer 210 in the flat display portion 100. By omitting the first electrode 2110 and the second electrode 2120 on the light modulation layer 210 in the flat display portion 100, the transmittance of the light modulation layer 210 can be improved, and the display luminance of the display panel can be improved.
In this embodiment, the dimming layer 210 is extended from the curved display portion 200 to the flat display portion 100, so that the dimming layer 210 may completely cover the display layer 300, so that the transition between the curved display portion 200 and the flat display portion 100 of the display panel is smoother, and the display effect at the transition is easy to adjust, thereby better improving the problem of light divergence or concentration.
In the display panel of the present application, the flat display portion 100 is provided with a linear polarizer, and the linear polarizer and the dimming layer 210 are arranged in the same layer; wherein, in the direction of the top view of the display panel, the linear polarizer is overlapped with the flat display part 100.
In this embodiment, the flat display portion 100 is provided with a linear polarizer, the curved display portion 200 is provided with a dimming layer 210, the linear polarizer and the dimming layer 210 are arranged in the same layer, and the linear polarizer and the dimming layer 210 are in contact with each other in a transition region between the flat display portion 100 and the curved display portion 200, and smooth transition is achieved.
The present embodiment can solve the problem of light divergence or concentration of the curved display section 200 by providing the dimming layer 210 only to the curved display section 200. Meanwhile, the linear polarizer is disposed on the flat display part 100, so that external ambient light can be converted into linear polarized light. Since the attaching process of the linear polarizer is simple compared with the manufacturing process of the dimming layer 210, the manufacturing process of the flat display portion 100 of the entire display panel can be simplified.
In this embodiment, the external ambient light enters the display panel, and is reflected by the display panel and then enters the eyes of the user, resulting in glare. Therefore, it is necessary to eliminate the part of light so that the display effect of the display panel is not disturbed by the external environment light.
In the display panel of the present application, referring to fig. 6, the display panel further includes a quarter wave plate 500, and the quarter wave plate 500 is disposed on a side of the display layer 300 near the dimming layer 210.
In this embodiment, referring to fig. 6, the display panel further includes a quarter wave plate 500, and the quarter wave plate 500 is disposed between the display layer 300 and the dimming layer 210.
In this embodiment, when the display panel includes the linear polarizer of the flat display part 100 and the dimming layer 210 of the curved display part 200, the quarter wave plate 500 is disposed in whole. Wherein, in the flat display part 100, the quarter wave plate 500 is positioned between the linear polarizer and the display layer 300, and in the curved display part 200, the quarter wave plate 500 is positioned between the dimming layer 210 and the display layer 300.
In this embodiment, when the display panel is formed of the light modulation layer 210 of the flat display portion 100 and the light modulation layer 210 of the curved display portion 200, the quarter wave plate 500 is disposed in whole. In both the flat display section 100 and the curved display section 200, the quarter wave plate 500 is located between the light modulation layer 210 and the display layer 300. In this embodiment, the dimming layer 210 disposed on the flat display portion 100 can achieve the effect of a linear polarizer, and converts natural light in the external environment into linearly polarized light.
In this embodiment, the quarter-wave plate 500 is disposed on the display layer 300, when ambient light is incident into the display panel, the ambient light is first converted into linearly polarized light by the linear polarizer, and the linearly polarized light is incident into the display layer 300 through the quarter-wave plate 500, reflected by the display layer 300, and emitted through the quarter-wave plate 500. After passing through the quarter wave plate 500 twice, the direction of the linearly polarized light is changed, the polarization direction of the linearly polarized light is perpendicular to that of the linear polarizer, and the part of light cannot be emitted from the front surface of the display panel. Therefore, glare caused by ambient light can be eliminated, and the display effect of the display panel is improved.
In the display panel of the present application, the material of the quarter-wave plate 500 may be liquid crystal.

In this embodiment, the display panel may further include a touch layer, where the touch layer may be separately disposed between the display layer 300 and the quarter wave plate 500, or may directly integrate a touch function into the display panel surface. The present application is not limited in this regard.
