Abstract
The utility model provides an LED display screen for playing sound and subtitles synchronously, which comprises a screen body, a master controller, a DVI data line, a power supply, a reticle, a power line, a framework, a rear cover and a built connecting line, wherein the screen body comprises a PCB driving circuit and an LED array; the master controller comprises a sending card, a displaying card and a receiving card; a sound device is connected on the LED display screen; and a sound control integrated circuit is additionally arranged on the PCB driving circuit. In the utility model, the sound control integrated circuit of a PCB circuit board is controlled by software, therefore, the LED display screen for playing the sound and the subtitles synchronously has the following technical effects that the structure is simple, the LED display screen can play the sound and the subtitles synchronously and can be made into the single color, double colors or full colors, and the application range is wide.
Description
Technical field
The utility model relates to a kind of LED display, specifically, relate to a kind of can synchronously playing sound and the LED display of captions.
Background technology
LED display is a kind of LED flat panel display product, can be used for display text, image, animation and TV, video program etc., have multiple editor and playing function, because advantages such as it has little power consumption, long service life, cost is low, brightness is high, fault is few, the visual angle is big, visual range is far away, become the information spreading tool of a new generation, it is compared with LCD, have the brightness height, cost is low and screen size can be pieced together the advantage of system as required with the LED cell board, and the scope of application is more extensive, can be installed in outdoor, partly outdoor and indoor; Can be divided into monochrome, dual base color and color LED display screen according to color.
But present LED display can't synchronously playing sound and captions, have therefore also influenced applying of LED display to a certain extent.
The utility model content
The purpose of this utility model is to solve the problem that prior art exists, and the LED display of a kind of synchronously playing sound and captions is provided.
The LED display of synchronously playing sound of the present utility model and captions, comprise screen body, primary controller, DVI data line, Switching Power Supply, netting twine, power lead, framework, bonnet and machine intraconnections composition, wherein shield body and comprise PCB driving circuit and led array, primary controller comprises transmission card, video card and receiving card, be connected with sound device on the LED display, on the PCB driving circuit, add the sound control integrated circuit in addition.
Preferably,
Said led array adopts 8 * 8 monochromatic display units to be spliced, and each point of array is furnished with ruddiness, green glow or a blue-ray LED.
Said led array adopts 8 * 8 double-colored display units to be spliced, and each point of array is furnished with red and green light LED.
Said led array adopts 8 * 8 double-colored display units to be spliced, each point of array is furnished with a green light LED, blue-ray LED and two red-light LEDs to be formed, and two red-light LEDs are composed in series after the branch circuit more in parallel with green light LED, two branch circuits of blue-ray LED.
The LED display of the utility model synchronously playing sound and captions, sound control integrated circuit by software control PCB circuit board, has following technique effect: simple in structure, can synchronously playing sound and captions, and can make monochrome, double-colored or full-color LED display, have wide range of applications.
Description of drawings
Come the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the LED display of embodiment 1 of the present utility model;
Wherein, 1 is LED display screen body, and 2 is primary controller, and 3 is framework, and 4 is sound device, and 5 is the PCB driving circuit, and 6 is led array.
Embodiment
Embodiment 1
As shown in Figure 1, the synchronously playing sound of present embodiment and the LED display of captions, comprise screen body 1, primary controller 2, DVI data line, Switching Power Supply, netting twine, power lead, framework 3, bonnet and machine intraconnections composition, wherein shield body and comprise PCB circuit board 5 and led array 6, primary controller comprises transmission card, video card and receiving card, be connected with sound device 4 on the LED display, on the PCB circuit board, add the sound control integrated circuit in addition.Wherein, led array adopts 8 * 8 monochromatic display units to be spliced, and each point of array is furnished with a red-light LED.
The structure of the synchronously playing sound of present embodiment and the LED display of captions is substantially the same manner as Example 1, and difference is that led array adopts 8 * 8 double-colored display units to be spliced, and each point of array is furnished with red and green light LED.
Embodiment 3
The structure of the synchronously playing sound of present embodiment and the LED display of captions is substantially the same manner as Example 1, difference is that led array adopts 8 * 8 double-colored display units to be spliced, each point of array is furnished with a green light LED, blue-ray LED and two red-light LEDs to be formed, and two red-light LEDs are composed in series after the branch circuit more in parallel with green light LED, two branch circuits of blue-ray LED.
The job step of the LED display of synchronously playing sound of the present utility model and captions is as follows:
1) the sound control integrated circuit by software control PCB circuit board by the software steering order of sounding, sends to the LED primary controller;
2) after primary controller was accepted instruction, transmission command was given LED display again;
3) the LED primary controller provides caption information, and therefore LED display realizes that sound and captions are synchronous owing to connected sound device.
