Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] figure 1 It is a structural schematic diagram of a display screen in the prior art. Such as figure 1 As shown, the frontmost layer of the display screen commonly used in the prior art is a liquid crystal display screen 110, on which there is a pixel array. The intensity of light transmission of each pixel unit is controlled by the angle, so as to realize the picture display of the LCD screen. Since the liquid crystal screen cannot actively emit light, a backlight unit is usually placed behind the liquid crystal screen, usually consisting of an LED light bar 120 and a light guide plate 130 . The LED light bar 120 is used to provide a light source, and the light guide plate 130 converts the light emitted by the LED light bar 12...

Abstract

The invention discloses a picture display method and device, and a head-mounted device. The picture display device comprises a liquid crystal display screen, a light emitting unit and a light shading unit which are arranged in order between the user sight and the external environment from inside to outside. The picture display device also comprises a control unit, which is connected with the liquid crystal display screen, the light emitting unit and the light shading unit. When the light shading unit is in the light transmission state, light from the external environment enters human eyes via the light shading unit and the liquid crystal display unit, and pictures on the liquid crystal display screen are displayed to users by means of the light from the external environment. When the light shading unit is in the light shading state, the enclosed space is formed between the light shading unit and the liquid crystal display unit, and pictures on the liquid crystal display screen are displayed to users by means of a light source provided by the light emitting unit. In this way, requirements on different application scenarios from users are satisfied. In addition, when the light shading unit is in the light transmission state, users directly perceive the external environment, thereby preventing the problem of resolution reduction for image processing. Furthermore, there is no delay, therefore improving the user experience.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a method and device for displaying images and a head-mounted device. Background technique [0002] The virtual reality device forms a virtual world through the content displayed on the screen, so that the user is completely isolated from the real world after wearing the virtual reality device; the augmented reality device displays relevant information on the basis of the real world seen by the human eye, so that the user can see to the real world overlaid with augmented reality information. In terms of design, virtual reality devices are more inclined to a closed display environment, while augmented reality devices are more inclined to an open display environment. [0003] At present, there are some virtual reality and augmented reality compatible devices on the market, which shoot the external environment through the camera, process the image and display it to the us...
