Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] In order to achieve the anti-peeping effect of the display panel, an embodiment of the present invention provides an optical substrate, which is provided with a light-transmitting unit corresponding to the pixel unit of the display panel, so that the incident light transmitted along a preset direction is transmitted and emitted to form a Bessel Bessel Bessel beam to ensure that when the optical substrate is applied to the display panel, the light passing through the display panel is modulated into a Bessel beam output, which has no diffraction angle and is emitted with anti-low visibility, and the field of view angle is limited within a certain range, so as to achieve anti- peep effect.

Abstract

The invention provides an optical substrate and a preparation method thereof and a display panel. The optical substrate is applied to the display panel and comprises a transparent substrate body and light-transmitting units arranged on the transparent substrate body, each light-transmitting unit corresponds to one pixel unit of the display panel, and the light-transmitting units are configured inthe mode that incident light transmitted in the preset direction penetrates through the light-transmitting units and is emitted out to form a Bessel light beam. According to the optical substrate, a plurality of light-transmitting units are arranged on the transparent substrate; each light-transmitting unit corresponds to one pixel unit of the display panel, so that incident light corresponding toeach light-transmitting unit is modulated into a Bessel light beam, the Bessel light beam can be applied to the display panel, the field angle of the display panel is limited within a certain range,and therefore the peep-proof effect is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical substrate, a preparation method, and a display panel. Background technique [0002] In the pursuit of high-resolution and low-power consumption of existing display devices, anti-peeping and low-visibility visibility have become a new technological innovation point in order to meet the increasing demand for privacy protection and the use of complex environments. [0003] Usually, the anti-peeping display of the display device is realized by improving the display principle and structure of the display panel, which is technically difficult, and will cause a series of cost increase problems such as energy consumption, and cannot be widely used. Contents of the invention [0004] The purpose of the technical solution of the present invention is to provide an optical substrate, a preparation method, and a display panel, which are used to realize the anti-peeping effect of...
