Problems solved by technology
[0002] Existing display devices mainly use two spatial light modulators to control the light emitted by the light source to achieve a high dynamic range display effect. There is generally a problem of low light efficiency in devices, and its light efficiency is about 50% of that of ordinary display devices, which may easily cause display devices to not achieve high peak brightness.
Another type of display device uses dynamic aperture technology to achieve high dynamic range display effects. The display device dynamically adjusts the size of the aperture to achieve dynamic contrast by analyzing the picture. way to achieve, it is impossible to obtain a higher contrast

Abstract
A display device, including a light source device, an optical processing component, a controller, and a spatial light modulator, wherein: the light source device includes a light source array formed by a plurality of light sources; the optical processing component includes sequentially arranged on the light source array and the shaping component and soft light component on the optical path between the spatial light modulator, the shaping component includes a shaping element array formed by a plurality of shaping elements, and the distance between every two adjacent shaping elements is the 5%-50% of the size of the shaping element; the controller is electrically connected to the light source device and the spatial light modulator, and is used to control the on / off and luminous brightness of each light source, and control the spatial light modulation The device modulates the light to achieve higher contrast and higher light efficiency.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Existing display devices mainly use two spatial light modulators to control the light emitted by the light source to achieve a high dynamic range display effect. There is generally a problem of low luminous efficiency in the display device, and its luminous efficiency is about 50% of that of ordinary display devices, which easily makes it difficult for display devices to achieve high peak brightness. Another display device uses dynamic aperture technology to achieve a high dynamic range display effect. The display device dynamically adjusts the size of the aperture to achieve dynamic contrast by analyzing the image. way to achieve, it can not achieve a higher contrast. Contents of the invention [0003] In view of this, the present invention provides a display device capable of achieving higher contrast ratio and higher...
