Embodiment 1

[0080] The present invention provides a display device, please refer to figure 1 , which is shown as a cross-sectional structure diagram of the display device, including an upper electrode layer 1, a base electrode layer 2, a lower electrode layer 3 and a plurality of light providing units 4, wherein the base electrode layer 2 is connected to the upper electrode layer 1 Below, the lower electrode layer 3 is connected under the base electrode layer 2 , and the light providing unit 4 is disposed under the lower electrode layer 3 .

[0081] Specifically, the base electrode layer 2 includes a plurality of zoom liquid lens cavities that penetrate the base electrode layer 2 up and down, and the upper electrode layer 1, the base electrode layer 2 and the lower electrode layer 3 together form a zoom lens cavity. In the liquid lens array, each zoom liquid lens cavity corresponds to a zoom liquid lens unit, and the main body of the base electrode layer 2 serves as the base electrode of ...

Embodiment 2

[0102] The display device of the present invention can be applied to various devices with display functions, such as televisions, computers, mobile phones and the like. As an example, see Figure 12 , is shown as a structural schematic diagram of a mobile electronic device 6 using the display device of the present invention. The mobile electronic device 6 may be a notebook computer, and its display screen at least includes an LED backlight layer, a liquid crystal layer and a zoom Liquid lens layer. In this embodiment, the display device can also optionally be configured with an eye tracker 601, a distance sensor 602, a display camera 603, or a wearable camera 604, so as to use the eye tracker 601 to find the position of the observer's eyes and measure the distance between the eyes and the position of the observer. The distance between the display device, or use the display camera 603 and the distance sensor 602 to measure the distance between the observer's eyes and the displ...

Embodiment 3

[0110] This embodiment adopts basically the same technical solution as Embodiment 1, the difference is that the light providing unit of the display device in Embodiment 1 is based on liquid crystal display (LCD) technology, and in this embodiment, the light providing unit adopts Light-emitting diode (LED) technology.

[0111] As an example, see Figure 15 , Figure 16 and Figure 17 , the light providing unit includes a light emitting diode 404 and a thin film transistor 405 from top to bottom, and the thin film transistor 405 is used to control whether the light emitting diode 404 is on or off, wherein, Figure 15 It is shown that the display device of this embodiment presents a schematic diagram of 2D color display in the state where no voltage is applied to the metal electrodes Figure 16 It is shown as a schematic diagram of the 2D color display presented by the display device of the present embodiment in the state of applying a voltage to the metal electrodes, Figure...

Abstract

The invention provides a display device and a display method. The display device comprises an upper electrode layer, a base electrode layer, a lower electrode layer and a plurality of light emitting units, wherein the base electrode layer is connected to the upper part of the upper electrode layer and comprises a plurality of variable-focus liquid lens cavities; oily liquid and conducting liquid are arranged in the cavities from bottom to top; an insulating hydrophobic membrane is arranged on the surface of the inner wall of each of the cavities; a plurality of discrete metal electrodes are arranged between the surface of the inner wall of each of the cavities and the insulating hydrophobic membrane for changing the optical axis inclination and the imaging focus length of a liquid lens, sothat the display device can present a two-dimensional or three-dimensional display mode; the lower electrode layer is connected to the lower part of the base electrode layer; and the plurality of light emitting units are arranged below the lower electrode layer and correspond to the positions of the variable-focus liquid lens cavities. The display device can freely switch between a 2D display mode and a 3D display mode, and can automatically and continuously change focus to relieve the eye fatigue of an observer; and the manufacturing of the liquid lens can be fused with the current industrial tablet display technology.

Description

technical field [0001] The invention belongs to the field of optical devices, and relates to a display device and a display method. Background technique [0002] Traditional Liquid Crystal Display (LCD for short) technology is based on the change of the refractive index of liquid crystal molecules to adjust the intensity of light passing through three filters of red, green and blue to display images. However, the image displayed by this method is two-dimensional (2D), and the amount of information transmitted is small. [0003] As the flat panel display market becomes increasingly saturated, the flat panel display market begins to seek new technologies to meet user needs. Three-dimensional (3D) display technology, as the next-generation mainstream display technology, has attracted more and more people's attention. In order to achieve 3D imaging effects, most cinema and television products use specially modified glasses. However, people generally do not tend to wear glasse...
