Embodiment 1

[0033] This embodiment provides an array substrate, the structure of the array substrate can be as follows figure 1 As shown, it includes: a base substrate 101 and a plurality of pixel units A located on the base substrate 101 , each pixel unit A includes: a transmissive area A1 and a reflective area A2 , and a reflective structure 105 is disposed in the reflective area A2 .

[0034] The above-mentioned array substrate 101 also includes: an optical element 106 disposed between the reflective structure 105 and the base substrate 101, the optical element 106 changes the propagation direction of the light incident from the back of the array substrate into the reflection area A2, so that the light from the The transmissive area A1 surrounding the reflective area A2 passes through.

[0035] In the array substrate provided in this embodiment, by setting the optical element 106 under the reflective structure 105, the optical element 106 can bypass the light incident on the reflective...

Embodiment 2

[0041] This embodiment provides an array substrate, the optical element 106 of which uses light refraction to make light bypass the reflective structure 105, and the structure of the array substrate can preferably be as follows figure 2As shown, the array substrate further includes: a flat layer 103 located between the optical element 106 and the reflective structure 105 . The structure of the optical element 106 preferably includes: a bottom surface that is flush with the side of the flat layer 103 close to the base substrate 101 and an arc surface opposite to the reflective structure 105; The side, that is, the curved surface is bent toward the base substrate 101; the refractive index of the optical element 106 is greater than that of the flat layer 103, so that light can be refracted toward the transmissive area A1.

[0042] When the light incident on the reflective area A2 from the back of the array substrate enters the flat layer 103 after passing through the optical ele...

Embodiment 3

[0066] This embodiment provides an array substrate, the optical element 106 of which utilizes the reflection of light to make light bypass the reflective structure 105, and the structure of the array substrate can preferably be as follows image 3 As shown, the array substrate further includes: a flat layer 103 between the optical element 106 and the reflective structure 105, the flat layer 103 has a groove opening toward the reflected structure 105, and the optical element 106 is located in the groove; the optical element 106 includes a bottom surface overlapping with the reflective structure 105 and a reflective surface overlapping with an inner wall of the groove, and the reflective surface reflects light to the transmissive area A1.

[0067] When the light incident on the reflective area A2 from the back of the array substrate passes through the optical element 106 and enters the flat layer 103, since the reflective surface of the optical element 106 has the characteristics...

Abstract

The invention provides an array substrate and a manufacturing method of the array substrate, and a transflective display device. The array substrate comprises an underlay substrate and a plurality of pixel units located on the underlay substrate. Each pixel unit comprises a radiolucent area and a reflection area, wherein a reflection structure is arranged in the reflection area. Each pixel unit further comprises an optical element arranged between the reflection structure and the underlay substrate. The optical element changes the propagation direction of light rays which are transmitted to the reflection area from the back face of the array substrate, and enables the light rays to be transmitted out from the radiolucent area at the periphery of the reflection area. According to the technical scheme, the optical element is arranged below the reflection structure, action is conducted on the light rays which are transmitted to the reflection area from the back face through the optical element so as to change the propagation direction of light rays, the reflection structure blocking the light rays is avoided, and the light rays are transmitted out from the radiolucent area at the periphery of the reflection area, so that the transmittance of the light rays is increased, and display brightness of the device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a transflective display device. Background technique [0002] In the current field of flat panel display technology, liquid crystal display devices occupy a dominant position due to their advantages of small size, low power consumption, and no radiation. According to different types of light sources (internal light source, external light source) used, liquid crystal display devices can be classified into three types: transmissive type, reflective type and transflective type. [0003] Among them, the transflective liquid crystal display device can use both the internal backlight light and the external ambient light when displaying the screen, and has the advantages of good visibility of the screen of the transmissive display device and low energy consumption of the reflective display device. , which can meet the use require...
