Problems solved by technology

But this invention has the following problems: the connection between the point light source and the graphic signal source requires a relatively complicated structure, so that the number of the rotating point light source is limited; Does not improve the clarity of the image, but instead produces a stretched displayed image that distorts the displayed image
These two reasons lead to the limited definition of this type of display device, so it is only suitable for displaying advertising text and simple pictures

Embodiment Construction

[0024] As shown in Figure 1, the display device based on the mirror includes a flat display mirror 2 arranged on the rotating mechanism 1, and a straight line on the mirror surface of the display mirror 2 is arranged parallel to the rotation axis of the rotating mechanism 1; at least A row of light source groups 4 composed of several point light sources 3 arranged in a straight line, the straight lines arranged by the light source groups 4 are fixedly arranged parallel to the rotation axis of the rotating mechanism 1; a control device 5, which controls the display The synchronous relationship between the rotational angular velocity of the mirror 2 and the pixel refresh of the light source group 4, and the brightness and darkness of each point light source 3 in the light source group 4 when controlling each pixel refresh according to the image signal; the display mirror 2 As a display screen itself, and a single mirror can be imaged. Wherein, the rotating mechanism 1 is an elec...

Abstract

The reflector-based display device comprise: two display mirrors (2, 2') on a rotator (1), at least one row of light source group (4, 4') composed by point light sources (3, 3') paralleled to the rotation axis of (1), and a controller (5) to control the synchronization relation between rotating angle of (2, 2') and frequency flash of (4, 4'). This invention can provide better resolution with simple structure.

Description

technical field [0001] The present invention relates to a display device based on a mirror, in particular a new display device designed mainly by using the reflection principle of light and the human visual retention effect. The device can be used in the fields of television, lighting advertisement and exhibition . Background technique [0002] With the development of technology, display technologies such as televisions have various forms, one of which is projection display technology. [0003] As far as the projection display technology is concerned, one of the methods is a video display device disclosed in Chinese patent document CN1370005A. The video display device includes a group of light-emitting units, and the light-emitting units emit a row of pixel light each time according to the pixel order, frequency and intensity under the control of the pixel storage controller. These light rays enter the light collector output through respective corresponding input ports in ...
