Abstract
The utility model relates to a display screen which uses an alternating current lighting bulb as a pixel light source, and a transparent waterproof cover of red, green and blue three primary colors is covered outside the bulb. A screen body of the display screen has the advantages of good wind penetration performance and simple structure, and displays the cartoon of color pictures and words. The utility model overcomes the defects of the ordinary electronic LED display screen, such as high cost, complex installation, great power consumption, difficult maintenance, etc., and improves the solution of manufacturing in bulk and installing the display screen.
Description
The utility model relates to a kind of display screen of energy display color picture and text animation, especially shields display screen simple for structure.
Its light-emitting component of present electronic display mainly is a LED, and the direct current that needs a series of equipment civil power to be become the specific voltage value uses for LED; LED display also needs the screen body is done the reinforcing of windproof, waterproof and radiating treatment or the like, makes LED electronic display complex structure.
The purpose of this utility model provides a kind of improved color animation display screen, makes it have succinct structure.
The purpose of this utility model is achieved in that the light source of being made of the display screen matrix unit the lighting bulb of AC-powered, the ground wire of each bulb, live wire connect the line scanning cable and the column scan cable of display screen respectively, the row, column scanhead cable directly is connected with the alternating current that civil power provides by power controller spare, control circuit is controlled the light on and off of bulb by the break-make of control row, column sweep signal, change pixel status, show the picture and text animation; Display screen matrix unit and row, column scanhead cable directly are fixed on the ventilative stilt.Like this, save parts such as transformation to power supply, rectification, filtering and saved windproof, waterproofing reinforcement and the radiating treatment that the display screen body is done again, reached purpose simple for structure.
The scheme that the utility model provides makes the display screen structure that shows the picture and text animation simple, has reduced equipment and parts, and then has improved utilization rate of electrical, has reduced the manufacturing cost and the installation cost of display screen, and has made things convenient for installation and maintenance.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the circuit connection diagram part of the utility model display screen display part.
The lighting bulb 7. that the lighting bulb 6. that 1. red column sweep traces, 2. green column sweep traces, 3. blue column sweep traces, 4. horizontal scanning lines 5. are covered with red transparent watertight lampshade among the figure is covered with the green transparent waterproof lampshade is covered with the lighting bulb of blue transparent watertight lampshade
4 identical pixel cells have been drawn among the figure with the annexation between remarked pixel.A pixel cell is formed in one group of bulb (5), (6), (7) that are covered with the colourful transparent waterproof lampshade, (5), (6), (7) can be that mercury lamp, sodium vapor lamp also can be incandescent lamps, show red, green, blue when bulb is bright respectively, control the just mutual collocation of these pixel three primary colours of may command of light on and off of these three bulbs, (6) were bright when for example (4) and (2) were effective simultaneously, put green glow; (4) and (5) effectively the time, (7) are bright simultaneously (1), (3), put purple light.The light intensity of length may command primary colours of control bulb light on and off time, the different primary colours collocation light intensity different with every kind of primary colours be capable of being combined to go out various coloured light.Between the line scanning cable and between every group of column scan cable of pixel cell very big space is arranged, utilize this space that pixel cell and cable directly are fixed on the ventilative stilt.Stilt is shaped as the shape of holding court from behind a screen, net form, grid shape, can be rigidity also can be flexible, for example with nylon rope according to pixels column pitch make the stilt of the type of holding court from behind a screen, pixel cell and cable directly be fixed on constitute display screen on the nylon rope; For example weave into woven wire again and do stilt with wire rope, vertical wire rope of every row pixel cell, transverse steel wire rope of every capable pixel cell constitutes display screen; The routine again aluminium section bar grizzly bar wall that utilizes old advertising signboard is as stilt, and according to pixels spacing removes some unnecessary grizzly bars if grizzly bar is too close, to increase ventilative amount, guarantees that ventilative sectional area summation partly is greater than 30% of display area.
Claims (3)
1, a kind of display screen, with dynamic scan mode display color picture and text animation, it is characterized in that: the light source of display screen matrix unit is made of the lighting bulb of AC-powered, pixel cell is connected with the column scan cable with the line scanning cable, and directly is fixed on the ventilative stilt.
2, display screen according to claim 1 is characterized in that: the ventilative stilt of display screen is the shape of holding court from behind a screen, net form, grid shape, and ventilative direction is perpendicular to the panel that shows, the sectional area summation of ventilative part is greater than 30% of display area.
3, display screen according to claim 1 is characterized in that: three lighting bulbs are arranged in each pixel cell of display screen, be covered with the transparent watertight cover of red, green, blue three primary colours respectively.
