Abstract

The utility model discloses a rotary-type high-resolution screen based on the LED pixel multiplexing technique, and the screen comprises a supporting pedestal, and a column display which is connected with the supporting pedestal through a rotary carrier. The column display also comprises a microcontroller, a storage module, a video data network module, a synchronizing network module, and a display array, wherein the storage module, the video data network module, the synchronizing network module and the display array are respectively connected with the microcontroller. The display array is formed by the fixed arrangement of a plurality of groups of three-primary color display units. Through the mode of pixel multiplexing, the screen provided by the utility model simplifies the structure of a system circuit, is easier to achieve, greatly reduces the cost while further increasing the display resolution, can achieve different resolutions through different combinations of three-primary colors according to different demands, and enables the display effect to be more flexible.

Description

A kind of rotary screen of high resolving power based on LED pixel multiplexing technology

Technical field

The utility model relates to a kind of display device, is specifically related to a kind of rotary screen of high resolving power based on LED pixel multiplexing technology.

Background technology

In order to reach good vision observing effect, once there is the design that planar LED screen is changed into column, make 360 degree all can watch image content, but column display area is larger, as with high costs as its luminescence unit in whole employing light emitting diodes, in order further to reduce costs, the patent No. is that 200420019290.6 patent has proposed a kind of columnar space-time dividing rotary screen, further have light emitting array is set at regular intervals on this display screen, and allow it by certain speed, rotate, by the control to each array displaying time and position, use the visual persistence effect of human eye, can form a complete display frame.Light emitting array in aforementioned display screen, normally by light emitting diode, formed, be positioned at the array on rotating carrier sidewall, display screen based on this technology, the resolution of its X-axis can be by software control, but the resolution in Y-axis depends on self size and reserved gap of wiring of LED, therefore comparatively coarse at the picture that this side up presents, affect picture total quality, Given this, the patent No. is that 200520133128.1 patent has proposed again a kind of high resolution pillar display screen, by luminescence unit is staggeredly placed, when rotation, utilize persistence of vision effect, make up the gap between luminescence unit, thereby demonstrate high-resolution picture.

Luminescence unit is staggeredly placed to put forward high-resolution mode, although can improving picture resolution, implementation complexity is higher, not only a plurality of LED array need to be accurately set on hardware, and need program to control the demonstration of each array; The setting of a plurality of LED array has also increased the cost of system in addition.

Summary of the invention

(1) technical matters that will solve

For addressing the above problem, the utility model proposes a kind of rotary screen of high resolving power based on LED pixel multiplexing technology, the light emitting array only consisting of a row luminescence unit, can effectively promote the resolution of rotary screen, reaches the display effect same with aforementioned techniques.

(2) technical scheme

A kind of rotary screen of high resolving power based on LED pixel multiplexing technology of the present utility model, comprises base for supporting and adopts the connected row display of rotating carrier; Described row display also comprises microcontroller and the connected memory module of difference, video data mixed-media network modules mixed-media, synchronizing network module and array of display; Described array of display forms by organizing three primary colors display unit stationary arrangement more.

Further, described three primary colors display unit is single three primary colors luminescence medium or is arranged and formed by primary colors red luminescence medium, green emitting medium and blue-light-emitting medium.

Further, described video data mixed-media network modules mixed-media is also connected with synchronizing network module.

(3) beneficial effect

Compared with prior art, it has following beneficial effect to the utility model:

The rotary screen of high resolving power based on LED pixel multiplexing technology of the present utility model, by the mode of pixel multiplexing, has been simplified circuit system structure, and screen is more easily realized, and has significantly reduced the cost of screen when further increasing display resolution; By different three primary colors combination and demand, can realize different resolution, make Showing Effectiveness On Screen more flexible.
