Embodiment Construction

[0062] In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0063] It should be noted that "on", "formed on" and "arranged on" mentioned in this article may mean that one layer is directly formed or set on another layer, or that a A layer is indirectly formed or disposed on another layer, ie there are other layers between the two layers. In this document, unless otherwise specified, the term "on the same layer" used means that two layers, parts, members, elements or parts can be formed by the same patterning process, and that the two layers, parts, members, Elements or parts are...

Abstract

The invention discloses a pixel structure, a display panel, a display method and a manufacturing method. The pixel structure is disposed between a first substrate and a second substrate and comprisesa light-emitting unit and a phase modulation unit, the phase modulation unit includes a waveguide into which light emitted by the light-emitting unit is incident, a first control electrode on the first substrate, and a second control electrode positioned on the second substrate and corresponds to the first control electrode; wherein the waveguide changes the refractive index in response to the voltage loaded by the first control electrode and the second control electrode so as to perform phase modulation on the incident light and emit the modulated light from the waveguide. According to the embodiment provided by the invention, through the phase modulation unit arranged in the pixel structure, the phase of the emergent light of a pixel in the pixel structure can be modulated so that holographic display is realized in the display panel, and the pixel structure has a wide application prospect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure, a display panel, a display method and a manufacturing method. Background technique [0002] The birth of 3D holographic display technology solves the problem of visual display in the field of virtual reality. It can give people an immersive feeling to a certain extent. Authenticity, its application fields are very extensive, such as medicine, architecture, scientific computing visualization, film and television entertainment, military training, video communication, etc. Different from two-dimensional display, 3D holographic display needs to adjust the phase of light during the display process. Phase control technology is one of the key technologies of 3D holographic display. [0003] In the prior art, LiNbO based on the principle of electro-optic effect is usually used 3 The phase modulator performs phase modulation on the light emitted from the dis...
