Embodiment Construction

[0023] In optical instruments, the angle of view refers to the angle formed by the lens of the optical instrument as the vertex, and the object image of the measured target can pass through the lens. The angle between the edge of the device and the point of view (eye).

[0024] When light is injected from one object into another material with different optical density, the propagation direction of the light is deflected. This phenomenon is called refractive phenomenon, and the unit indicating the magnitude of this refractive phenomenon (refractive power) is diopter (abbreviated as "D"). 1D refractive power is equivalent to focusing parallel light rays on a focal length of 1 meter.

[0025] Such as figure 1 , figure 2 Shown is a method for adjusting the viewing angle of a display device. The light-emitting side of the display device is provided with a plurality of microlenses distributed in an array, and the diopter of the microlenses can be changed when different voltages ...

Abstract

The invention provides a method and a system for adjusting a view field angle of a display device. A plurality of micro-lenses distributed in an array are arranged on the light emergent side of the display device; the diopter of each micro-lens can be changed when different voltages are applied to the micro-lens; corresponding relationships between the voltages applied to the micro-lenses and the diopters of the micro-lenses are obtained; the voltages applied to the micro-lenses are adjusted to adjust the diopters of the micro-lenses; and the view field angle of the display device is adjusted according to the diopters of the micro-lenses. In the whole process, the diopter of each micro-lens can be changed when the different voltages are applied to the micro-lens, so that the diopters of the micro-lenses can be adjusted by adjusting the voltages applied to the micro-lenses; and the micro-lenses are distributed in an array on the light emergent side of the display device, so that the view field angle of the display device can be effectively adjusted by adjusting the diopters of the micro-lenses.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a method and system for adjusting the viewing angle of a display device. Background technique [0002] The general display technology, whether it is LCD (Liquid Crystal Display, liquid crystal display) or OLED (Organic Light-Emitting Diode, organic electro-laser display), cannot freely adjust the display viewing angle according to the needs of users. For general LCD display equipment, if it is necessary to adjust the display viewing angle, it is mainly through the flip angle of the liquid crystal molecules and the cooperation of the polarizer to obtain a predetermined viewing angle. Once the product is completed, its corresponding maximum display angle has been determined. , the end user cannot freely and intelligently adjust the viewing angle of the display device according to needs. [0003] In some special scenarios, if the user needs to protect the display content fr...
