Background technology:

The arrival of informationized society; Promoted the development of present information display technique; Lifting along with LED and LCD material technology and technology; LED display becomes one of main product of FPD with outstanding advantage, and combines network technology and wireless communication technique, is used widely in socioeconomic many fields.Information screen on the market mainly is combination (the top display text information by LED display board and rolling lamp box now; The rolling painting canvas is play in the lower part); Or the LCD electronic display is play-overed advertisement video; The former mode of display message is more single, through the painting canvas playing advertisements, has satisfied not the requirement of resident to visual effect.Therefore in addition, present LCD backlight technology is also not overripened, is also coming with some shortcomings aspect efficient and the security, adds the cost height, is not suitable in the sub-district or the latter's LCD electronic display is installed in the roadside, road.

The utility model content:

The utility model provides a kind of LED_LCD_ painting canvas multimedia display screen; Be by the combination of wireless LED screen, rolling painting canvas lamp box and LCD display, can play rolling painting canvas picture and video dynamic menu, can either overcome the above-mentioned deficiency of general information screen; Remedy the defective of the existing approach that releases news; Satisfy the higher demand of people to cultural life, again can be dexterously with electric machines control technology, look the screen display technique and automatic switchover technology combines, be a kind of innovative product.

A kind of LED_LCD_ painting canvas of the utility model multimedia display screen comprises wireless LED screen control card 1, LED screen display board 2, painting canvas controller 3, painting canvas 4, player 5, LCD display 6, luminance sensor 7, video communication line 8 and outside framework 9.Wireless LED screen control card 1 lets information on LED screen display board 2, show through wireless network receiving control information and display message; Wireless LED screen control card 1 control painting canvas controller 3, painting canvas controller 3 management painting canvas 4; Wireless LED screen control card 1 sends information to player 5 through video communication line 8, and player 5 plays back on LCD display 6 through cable network or wireless network receiving control information and video information.It is characterized in that: (1) painting canvas 4 and LCD display 6 shared issue planes.In the rolling painting canvas, wherein there is width of cloth centre that a window is arranged, when rolling painting canvas 4 forwards this width of cloth to, just can expose the LCD display 6 of back, displaying video; (2) detect the brightness of external environment through luminance sensor 7, automatically switch to rolling painting canvas 4 interfaces or LCD display 6 interfaces: mainly be to set a value, when extraneous brightness is higher than this value, will automatically switch to the rolling canvas interface; Otherwise, when being lower than this value, then automatically switch to the LCD display interface, to adapt to extraneous lightness environment.(3) under the high light environment, 4 pairs of LCD displays 6 of painting canvas play a protective role.

Wherein said wireless LED screen control card 1, LED screen display board 2, painting canvas controller 3, painting canvas 4, player 5, LCD display 6, luminance sensor 7, video communication line 8 all are installed in outside framework 9 inside; The first half is a wireless LED screen 10, comprises that LED screen control card 1, LED shield display board 2; The latter half is that the painting canvas lamp box 11 that wherein rolls comprises painting canvas controller 3, painting canvas 4 by the combination of rolling painting canvas lamp box 11 and LCD display 12; LCD display 12 comprises player 5 and LCD display 6, is installed in the back of rolling painting canvas lamp box.

The advantage of the utility model is: luminance sensor can detect the brightness value of extraneous light automatically, sends this device to, and this device can be regulated play mode automatically according to the brightness value height.Under the daytime high light condition, watch LCD display can influence visual effect, the people is difficult for seeing clearly, and playing rolling painting canvas effect can be better, at this moment, and painting canvas operate as normal and LCD display is not worked.Simultaneously, can LCD display be adjusted into the back light of suitable illumination, as the backlight of rolling painting canvas.Painting canvas can be avoided the direct projection of sunlight again, and LCD display is shown good protective action.During overcast and rainy light was than dark or night, playing the LCD display effect can be better, at this moment; The rolling painting canvas can run to the specified window position automatically; Can displaying video programs, let the public enjoy more intuitive dynamic effect, watch picture more clearly; Also can eliminate people's visual fatigue, bring amusement and leisure to them.

The beneficial effect of a kind of LED_LCD_ painting canvas of the utility model multimedia display screen is: on the one hand; Meteorological department and functional government departments can send to information such as weather forecast, early warning information, documentary whip bulletin, highlight on a kind of LED_LCD_ painting canvas multimedia display screen; Form through literal shows on the LED display board, lets the public can obtain information in time, efficiently; What business information and public service ads can move in circles on the other hand plays in rolling painting canvas lamp box, enlarges advertising effect.Simultaneously; Through being connected of player and broadband internet or 3G; Can be on LCD display displaying video, let the resident watch video frequency program and dynamic advertising information, appreciate more directly perceived, image, dynamic menu clearly; Eliminate people's visual fatigue, also can be used as a kind of mode of public entertainment and leisure.This device is fit to be installed in public places such as road, station, sub-district, market, airport, school, the administration for industry and commerce, government department, is used for information issue, advertising and amusement and leisure.
