Embodiment Construction

[0031] The specific implementation manner of the display device provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Wherein, the thickness and shape of each structure in the drawings do not reflect the true scale of the display device, but are only intended to schematically illustrate the content of the present invention.

[0033] An embodiment of the present invention provides a display device, such as figure 1 As shown, it includes: a display panel 1, a collimating film structure 2 and a liquid crystal lens structure 3 arranged in sequence on the light-emitting side of the display panel 1, and an eye tracking unit ( Not shown in the figure); Wherein, the initial display gray scale value of each sub-pixel in the display panel 1 is the same and is the maximum value;

[0034] The collimating film structure 2 is used to modulate the light emitted by the display panel 1 to form collimated lig...

Abstract

The invention discloses a display device. The display device comprises a display panel, a collimation membrane material structure, a liquid crystal lens structure and a human eye tracing unit for determining the positon of an observer in front of the liquid crystal lens structure, wherein the collimation membrane material structure and the liquid crystal lens structure are sequentially arranged on the light outlet side of the display panel, initial display gray-scale values of sub-pixels in the display panel are same and are maximum values, the collimation membrane material structure is used for modulating light emitted by the display panel to form collimation light, the liquid crystal lens structure is used for refracting the propagation direction of the collimation light corresponding to the sub-pixels to the position determined by the human eye tracing unit according to the position determined by the human eye tracing unit, the gray-scale values required to be displayed by the sub-pixels and the light intensity proportions corresponding to the gray-scale values required to be displayed by the sub-pixels. The display device combines a human eye tracking technology, determines the light-emitting directions of the pixels in the display panel, centralizes the light to the receiving position of the human eye, effectively improves the light effect utilization rate and reduces the power consumption.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device. Background technique [0002] At present, the display technology has reached a certain bottleneck, nothing more than a larger display size, more delicate resolution, and a breakthrough in the display method is urgently needed. [0003] Generally, the display panel includes a liquid crystal display (Liquid Crystal Display, LCD) panel, an electroluminescent display (Electroluminescent Display, ELD) panel, and the like. When people watch directly in front of them, because the light emitted by LCD panels, ELD panels or other panels is divergent light, the human eyes only passively receive part of the light ratio, resulting in low light utilization efficiency. This problem becomes more and more obvious as the size of the display panel continues to increase. [0004] Therefore, how to improve light efficiency utilization and reduce power consumption is a technical ...
