Problems solved by technology

[0003] At present, the Chinese patent, its patent number is 201210196780.2 "wireless micro-display system", the image data transmission mode of the image sending end and image receiving end of the system is based on image frame transmission, the disadvantage of this system is that the image sending end needs to continuously send The image data is sent to the image receiving end, which makes the wireless receiving end in the image receiver work continuously, and the power consumption generated is too large to work for a long time
And once the image sending end stops sending, the image receiving end cannot receive image data, and the image on the microdisplay screen will disappear immediately

Embodiment 1

[0027] See Figure one , This low-power wireless micro display system includes an image sending end and an image receiving end. The image sending end sends data to the image receiving end through a wireless communication protocol; the image sending end is used to generate an image source, and the image source generator (101) Connected to the image transmitter (102), and there is a main controller (103) connected to the image source generator (101) and the wireless sending end, the image source generator (101) generates images, and the main controller (103) is used to control The image source generator (101) generates the resolution of the image and the switch of the wireless network, the image transmitter (102) sends the image produced by the image source generator (101) wirelessly; the image receiving end is used to receive and display the image, It consists of an image receiver (104) connected to a micro display (105), and an image receiver (104) connected to a frame controlle...

Embodiment 2

[0029] This embodiment is basically the same as the first embodiment, and the special features are:

[0030] In the above-mentioned low-power wireless micro-display system, the main controller is composed of FPGA / CPLD (201) or a dedicated chip connected to the liquid crystal display (204), image source control terminal (202) and wireless transmission control terminal (203). The power interface (205) constitutes.

[0031] In the above-mentioned low-power wireless micro display system, the image sending end sends image data to the image receiving end through a wireless communication transmission protocol. The transmission method is based on image content transmission. When the image data of the image sending end changes, the image sending end The image data is transmitted to the image receiving end. When the image data has not changed, the image sending end does not send data.

[0032] In the above-mentioned low-power wireless microdisplay system, the image transmitter (102) is compos...

Embodiment 3

[0038] In the above-mentioned low-power wireless micro-display system, the main controller is a CPLD (201) chip connected to the liquid crystal display (204), the image source control terminal (202) and the wireless transmission control terminal (203) plus a power interface ( 205) Composition. The main controller is used to control the liquid crystal display, the image source, the image encoding module and the wireless sending end. The main controller interface is set with resolution and wireless network switch functions. There are three options for the above resolution, and two options for the wireless network switch, see Figure 2 to Figure 3 .

Abstract

The invention relates to a low-power-consumption wireless micro-display system comprising an image sending terminal and an image receiving terminal. The image sending terminal and the image receiving terminal carry out data transmission based on a wireless communication protocol. The image sending terminal is used for generating an image source; an image source generator is connected with an image sender; and the image source generator and a wireless sending terminal are connected by a main controller. The image receiver is used for receiving and displaying an image; the image receiver is connected with a micro-display unit; and the image receiver is connected with a frame controller and a display controller is connected with the micro-display unit and the frame controller. According to the invention, with a frame buffer memory, the power consumption of the system is substantially reduced; and the lasting working time of the system can be increased.

Description

Technical field [0001] The invention relates to a low power consumption micro-display system based on frame buffer memory for wireless data transmission, which comprises an image sending end and an image receiving end. Background technique [0002] A microdisplay is a display with a relatively special form. The display with a diagonal size of less than 3.3cm is usually called a microdisplay. Its physical size is small, and the pixel pitch is only about ten microns, but it can be displayed on a large screen. Micro-displays are widely used in various consumer electronics, such as micro-projectors, head-mounted 3D high-definition micro-displays, head-mounted medical systems, military can be used in the Air Force pilot helmet system, the army individual helmet system. [0003] At present, the Chinese patent, its patent number is 201210196780.2 "Wireless Micro Display System". The image data transmission method of the image sending end and the image receiving end of this system is base...
