Embodiment Construction

[0026] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and details of the light-emitting module and display screen proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Its effect is described in detail below.

[0027] The liquid crystal display controls the deflection state of the liquid crystal molecules through the voltage to regulate the amount of light transmitted by the backlight source, thereby displaying a picture with a specific color and brightness distribution. Contrast is an important parameter to measure the display quality of LCD screen. Contrast is usually defined as the brightness ratio of the bright state picture (the red, green, and blue sub-pixels are all the highest gray scale) to the dark state picture (the red, green, and blue su...

Abstract

The invention discloses a light-emitting module and a display screen, and relates to the field of display technology. The main purpose is to collimate the light emitted by the light-emitting component by setting a light-collimating component, so as to improve the display performance. The main technical solution of the present invention is: a light-emitting module, the module includes: a light-emitting component and a light collimation component, the light collimation component is located on the side of the light-emitting Scattered light is collimated. The present invention is mainly used to provide backlighting.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting module and a display screen. Background technique [0002] In the prior art, in order to make the light incident on the liquid crystal display panel collimated, a light-trapping component is used to capture the light emitted from the backlight. The light-trapping component is usually a light-trapping grating, and the light-trapping component Diffraction and / or reflection, so that the light emitted through the light-taking grating has a certain degree of collimation. However, factors such as the diffraction of the small holes of the light-taking grating and the process deviation during the processing of the light-taking grating will affect the collimation of the light emitted from the light-taking grating, resulting in a divergence angle of the light. [0003] Therefore, the width of the light-shielding layer needs to be made very large, so as to avoid light lea...
