Problems solved by technology

With the rapid development of LED projectors, low-brightness projectors are light, convenient, and energy-saving, but it is difficult to project ideal images during the day
In order to reduce the interference of ambient light on the display surface, there are baffles on both sides and above the display surface, which can solve some problems to a limited extent. For larger screens, it is difficult to implement

Embodiment Construction

[0022] The real-time mode of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] 1. A projection screen capable of reducing ambient light on a display surface, which includes: a projection screen, characterized in that a plurality of blades 3 perpendicular to the imaging layer are arranged on the projection screen 1 .

[0024] According to the source of light in the use environment, the blades can choose horizontal slices 3 or vertical slices.

[0025] 2. A projection screen for reducing ambient light on a display surface according to claim 1, wherein the blades 3 and the imaging layer 1 of the projection screen are made of rubber materials.

[0026] 3. A projection screen capable of reducing ambient light on the display surface, comprising: a projection screen, characterized in that: on the projection screen 1, vertical and horizontal blades perpendicular to the imaging layer of the projection screen are set to form ...

Abstract

The invention provides a product capable of reducing ambient light for a display surface, which relates to a device for reducing interference of the ambient light by blocking and is used for a display or a projection screen. The invention aims to provide a plurality of products which are prepared by a method for reducing the interference of the ambient light for the display surface, wherein the products can be used on various displays or projection screens so as to ensure that the better viewing effect of the display surface in an environment with enough light can be achieved. The projection screen capable of reducing the ambient light for the display surface comprises a projection screen and is characterized in that: longitudinal and horizontal blades which are vertical to the projection screen are arranged on a projection screen 1 so as to form grids 2. By blocking light with the blades or grids, the projection screen capable of reducing the ambient light for the display surface can ensure that the ambient light cannot be directly irradiate on the screen but forms a plurality of dark points or a dark line on the display surface, so that the light intensity of natural light to the screen is reduced, and a projector with weaker light intensity can also image clearly.

Description

technical field [0001] The invention relates to a device for reducing ambient light interference by means of blade shielding, which is used for displays and projection screens. Background technique [0002] Any kind of display will affect the viewing effect in a well-lit environment. Especially for projection, if you want to see clearly during the day, you need to increase the brightness to make the projector project a dazzling image. If it is under the condition of sunlight, it cannot be viewed, because the current display does not have the function of reducing ambient light. Effectively reducing the ambient light on the display surface will improve the visual effect. With the rapid development of LED projectors, low-brightness projectors are light, convenient, and energy-saving, but it is difficult to project ideal images during the day. In order to reduce the interference of ambient light on the display surface, there are baffles on both sides and above the display sur...
