Problems solved by technology

[0002] The existing mainstream display technology is liquid crystal display technology, but liquid crystal display itself still has a lot of shortcomings. First, the structure is complex: each pixel needs three units to form, which is prone to dead pixels; second, there are problems of "observation angle", color Low domain coverage, false display
The plasma display method consumes a lot of power, heats up when working, and costs high
Compared with the above two methods, laser display has great advantages in power consumption and display effect, but due to the restriction of "scanning bottleneck", the performance and cost of laser TV cannot meet the requirements of commercialization
In addition, the existing display screens do not consider the screen interaction function

Embodiment 1

[0027] Embodiment 1 Embodiment of "T" shaped optical switch

[0028] Please refer to figure 1 , 2 , 3, figure 1 The structure and function of the "T" shaped optical switch are shown. It has three ports. Port A and port B are on the same straight line. The direction of port C is perpendicular to the straight line where port A and port B are located. This optical switch has optical path conversion Function, the light entering from port A can be controlled to choose to exit from port B or port C; figure 2 , 3 It is the concrete embodiment of two kinds of micromechanical "T" shaped optical switches.

[0029] figure 2 The "T"-shaped optical switch is mainly composed of a stretchable base and a reflector. The stretchable base can be composed of an electromagnet and an armature sandwiching an elastic material. The reflector is fixed on the armature, so that by controlling the electrical signal applied to the base The state of the optical switch can be controlled: when the coi...

Embodiment 2

[0032] Embodiment 2 "T" shape optical switch array embodiment

[0033] Please refer to figure 1 with Figure 4 , the optical switch array is composed of multiple figure 1 The "T" shaped optical switch shown is formed by combining connections. figure 1 A plurality of such "T" optical switches (the lower limit is 1 and the upper limit is not limited) are connected in sequence, and the port B of the first "T" optical switch is connected to the port A of the second "T" optical switch. The port B of the second "T" shaped optical switch is connected to the port A of the third "T" shaped optical switch, and so on, all the ports C of the "T" shaped optical switches point to the same direction, so that Form an optical switch chain. In the three-dimensional Cartesian space coordinates, one optical switch chain is placed along the y-axis. For the convenience of expression, it is called the y-chain. Any number of optical switch chains is placed along the z-axis. For the convenience of...

Embodiment 3

[0034]Embodiment 3 Embodiment of display screen with interactive function

[0035] Please refer to Figure 5 with Image 6 , for the sake of convenience, here the optical switch array 7 adopts a structure of 8 rows×8 columns, and the principles of other structures are similar. The "column address signal" terminal and "row address signal" of the drive module 5 (here composed of two serial-in-parallel-output chips 74HC595), the control terminal of the display light source 2, and the electrical signal output terminal of the photosensitive unit 4 are connected with the processor 1 respectively. (STC89C51 is selected here) connected to different input / output ports. The display light source 2 here can be composed of a group of tri-color LED light sources or laser light sources and a light mixer. When displaying, processor 1 controls the display light source according to the information of the video signal 2 emit light of a specific color, and enter the main port of the optical swi...

Abstract

The invention belongs to the field of display manufacturing, and particularly discloses an optical switch array and a display screen with functions of scanning and interaction formed by the optical switch array. The optical switch array comprises an optical switch chain which is arranged along the y axis in the three-dimensional rectangular coordinate system and a plurality of T-shaped optical switch chains which are arranged parallel to the z axis. The display screen structurally comprises a processor (1), a display light source (2), a light splitting unit (3), a photoconductor unit (4), a driving module (5) and a divergent unit (6); the display screen with the functions of scanning and interaction formed by the optical switch array is characterized in that the display screen is further provided with the optical switch array (7), and through controlling of the status of each T-shaped optical switch in the optical switch array (7), direct light display and the functions of scanning and interaction are achieved. According to the optical switch array and the display screen with the functions of scanning and interaction formed by the optical switch array, the structure is simple, the running power consumption is low, service life is long, the display color gamut is about the same as a laser television, the image quality is high, and the functions of scanning and interaction are achieved as well.
