Embodiment 1

[0036] An embodiment of the present invention provides an array substrate, including a plurality of pixel units distributed in a matrix, and a light concentrating element is provided in the display area of ​​each pixel unit, and the display area is a light-transmitting area or a light-emitting area of ​​each pixel unit , the light concentrating element is arranged on the light output path of the array substrate.

[0037] In the array substrate in this embodiment, since the display area of ​​each pixel unit is provided with a light-condensing element, the outgoing light needs to pass through the light-condensing element, and the refractive index of the light-condensing element is relatively large, so that the outgoing light has a smaller The angle is emitted from the light-emitting surface of the array substrate, which has the effect of concentrating the emitted light, thereby reducing the viewing angle of the display device and realizing the protection of personal privacy or bu...

Embodiment 2

[0039] On the basis of Embodiment 1, this embodiment provides an array substrate for OLED display devices, such as figure 1 As shown, the array substrate further includes a medium layer adjacent to the above-mentioned light-condensing elements 2 , the medium layer is located between adjacent light-condensing elements 2 , and the refractive index of the light-condensing elements 2 is greater than the refractive index of the medium layer. The array substrate also includes: a plurality of OLED light emitting units 1 arranged in a plurality of pixel units, and each light concentrating element 2 is arranged between each OLED light emitting unit 1 and the light emitting surface of the array substrate.

[0040] Specifically, the array substrate includes a first substrate 31, a thin film field effect transistor (Thin Film Transistor, TFT) is disposed on the first substrate 31, a first protection layer 41 is disposed on the TFT, and the first protection layer 41 is used to protect the ...

Embodiment 3

[0049] On the basis of Embodiment 1, this embodiment provides an array substrate, the array substrate is an array substrate of a liquid crystal display, such as Figure 7 As shown, different from the OLED display device in Embodiment 2, in the liquid crystal display device, the outgoing light is provided through the backlight module under the array substrate, so the array substrates are all located on the light exit path, and the light concentrating element 2 can be arranged on the array substrate In any layer above, as long as each light concentrating element 2 is located in the display area of ​​each pixel unit. Specifically, the array substrate includes a first substrate 31 on which pixel electrodes ( Figure 7 not shown in ) and the light-gathering element 2, the light-gathering element 2 can be arranged above or below the pixel electrode; the pixel unit on the color filter substrate includes a color resin 7 and a black matrix 8, the black matrix 8 is used to block light, ...

Abstract

The invention discloses an array substrate, a color film substrate and a display device, which relate to the technical field of display. Protection of privacy or business secret is realized by reducing the view angle of the display device. The array substrate comprises a plurality of pixel units which are distributed in a matrix form, wherein the display area of each pixel unit is provided with a light gathering element; and the light gathering elements are arranged on the light emitting path of the array substrate. The color film substrate comprises a plurality of pixel units which are distributed in a matrix form, and the display area of each pixel unit is provided with a light gathering element. The display device comprises the array substrate or the color film substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a color filter substrate and a display device. Background technique [0002] The current liquid crystal display or Organic Light-Emitting Diode (OLED) display has advantages such as wide viewing angles, and is generally used in mobile communication terminals, Personal Digital Assistants (Personal Digital Assistant, PDA), tablet computers or notebook computer lamps. However, for individual users who pay attention to privacy or in some business occasions, due to the need of confidentiality, it is not expected that the viewing angle of the display is too large, but the existing display cannot meet the requirement of a narrow viewing angle. Contents of the invention [0003] The invention provides an array substrate, a color filter substrate and a display device, which can protect personal privacy or business secrets by reducing the viewing angle of the...
