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

Display equipment comprises a light source device, an optical processing assembly, a controller, and a spatial light modulator, wherein: the light source device includes a light source array formed ofa plurality of light sources; the optical processing assembly comprises a shaping assembly and a soft light assembly which are sequentially arranged on a light path between the light source array andthe spatial light modulator, the shaping assembly comprises a shaping element array formed by a plurality of shaping elements, and the distance between every two adjacent shaping elements is 5%-50% of the size of the shaping elements; and the controller is electrically connected with the light source device and the spatial light modulator, and is used for controlling the on / off and the light emitting brightness of each light source and controlling the spatial light modulator to modulate light, so that relatively high contrast ratio and relatively high light efficiency can be realized.
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...
