Problems solved by technology

However, when the existing projection screens are used, they are often disturbed by ambient light; when the ambient light is stronger, the projection screen will become whiter and grayer, which will cause the contrast ratio of the projection screen to fail to meet the requirements, thus causing the audience to see clearly. thereby losing the basic presentation effect

Embodiment Construction

[0041] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0042] Such as Figure 1 to Figure 15 As shown, the main point of the reflective anti-light projection screen of the present invention is that it is provided with a first microstructure 11 and a second microstructure 21 inside, wherein the first microstructure 11 is used to absorb ambient light, and the second microstructure The structure 21 is used to reflect projection light, thereby reducing the loss of projection light and reducing the interference of ambient light, thereby improving the display effect of the reflective anti-light projection screen and improving the brightness and contrast of the reflective anti-light projection screen.

[0043] Specifically, such as Figure 1 to Figure 5 As shown, the reflective anti-light projection screen of the present invention includes a first functional layer 10 and a seco...

Abstract

Disclosed is a reflection-type light-resistant projection screen. The reflection-type light-resistant projection screen is characterized by comprising a first functional layer and a second functionallayer, wherein a plurality of first micro structures are arranged in the first functional layer at intervals, and a first light transmitting part is arranged between the first micro structures; a plurality of second micro structures are arranged in the second functional layer at intervals, and the second micro structures are provided with reflecting surfaces used for reflecting light rays; a second light transmitting part is arranged between the second micro structures; and the first light transmitting part and the second light transmitting part are made of light-transmitting materials. The reflection-type light-resistant projection screen is internally provided with the first micro structures for absorbing light and the second micro structures for reflecting light, wherein the second micro structures are used for reflecting the projection light so as to realize parallel light, so that the projection light loss is reduced; the first micro structures are used for absorbing ambient lightand reducing the interference of ambient light. According to the projection screen, the display effect of the reflection-type light-resistant projection screen can be greatly improved, and the contrast ratio and the brightness of the reflection-type light-resistant projection screen are improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the projection field, in particular to a reflective anti-light projection screen capable of improving projection display effects. [0003] 【Background technique】 [0004] A projection screen is a tool that cooperates with a projector to display images, video screens, etc. It is usually used in commercial advertisements, teaching, office, home or theater entertainment, etc. As an LCD screen that is also used to display images, in the case of large-scale demand, the cost of the LCD screen is high and it is not easy to carry and store, and it cannot be stored immediately when not in use; and the price of an LCD screen larger than 50 inches Expensive, not conducive to the purchase and use of ordinary families; in addition, when watching LCD screens for a long time, human eyes are also easily affected by radiation, which is not conducive to human health. However, compared with LCD screens, projection screens of the same siz...
