Abstract
The utility model discloses a transparent LCD projector. The transparent LCD projector comprises a driving board which is used for processing audio and video signals, a transparent liquid crystal screen which is connected with the driving board and used for displaying the video signals processed by the driving board, a power amplifier circuit which is connected with the driving board and used for amplifying the audio signals processed by the driving board and outputting the audio signal to a loudspeaker, a power supply processing module which is connected with the driving board and used for providing power for the driving board and the power amplifier circuit, and an interface circuit which is connected with the driving board and used for receiving external video and audio signals and transmitting the external video and audio signals to the driving board. The transparent liquid crystal screen does not need to be lightened by a backlight circuit, and pictures can be displayed by only natural light, so the transparent LCD projector with the structure above has advantages of high brightness, good stability, low energy consumption, and the like, and has wide market prospects in the LCD projection equipment field.
Description
Technical field
The utility model relates to the LCD projector equipment, relates in particular to a kind of transparent LCD projecting apparatus.
Background technology
Development along with science and technology, a feast for the eyes LCD projecting apparatus has appearred on the market, the display part of these LCD projecting apparatus is comprised of a backlight and liquid crystal display screen mostly, the 12V direct voltage is changed into the High Level AC Voltage of 1500～1800V by backlight to light the backlight of screen, such LCD projecting apparatus, be subjected to the impact of backlight brightness constancy, picture is easily fuzzy, and cost is high, power consumption is large.
The utility model content
The technical problems to be solved in the utility model is, the transparent LCD that a kind of brightness is high, energy consumption is low projecting apparatus is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
A kind of transparent LCD projecting apparatus, it includes a drive plate, for the treatment of video and audio signal; One transparent liquid crystal screen, it connects described drive plate, is used for showing the vision signal after this drive plate is processed; One power amplifier, it connects described drive plate, is used for amplifying the audio signal after this drive plate is processed and exports loud speaker to; One power supply processing module, it connects described drive plate, for this drive plate and described power amplifier provide power supply; One interface circuit, it connects described drive plate, is used for receiving external video and audio signal and being sent to described drive plate.
In the above-mentioned transparent LCD projecting apparatus, described interface circuit is any one or a few the combination in TV interface, AV interface, YPRPB interface, VGA interface, HDMI interface and the USB interface.
After transparent LCD projecting apparatus disclosed in the utility model, its drive plate are processed outer video signal, be shown on the transparent liquid crystal screen, this transparent liquid crystal screen does not need lighting of backlight circuit, only just can display frame by natural daylight.Therefore, the LCD projecting apparatus of this structure has that brightness is high, a good stability, low power consumption and other advantages, has wide market prospects in LCD projector equipment field.
Description of drawings
Fig. 1 is the electrical block diagram of transparent LCD projecting apparatus.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the disclosed transparent LCD projecting apparatus of the utility model includes a drive plate 7, transparent liquid crystal screen 11, one power supply processing module 8, an interface circuit 12 and a power amplifier 9.The periphery of drive plate 7 connects respectively transparent liquid crystal screen 11, power supply processing module 8, interface circuit 12 and power amplifier 9.
Wherein, interface circuit 12 is used for the video and audio signal of outside is sent to drive plate 7, interface circuit 12 can be with lower interface: the combination of one or more in TV interface 1, AV interface 2, YPRPB interface 3, VGA interface 4, HDMI interface 5 and the USB interface 6, these interfaces can make the LCD projecting apparatus receive the multi-signals such as analog signal, digital signal, high-definition signal.In other embodiments, interface circuit can also be expanded video or the audio signal interface of other types.
After drive plate 7 is processed the vision signal that receives, the output Low Voltage Differential Signal is to transparent liquid crystal screen 11, when there is light in the back side of transparent liquid crystal screen 11, video pictures just can shield 11 at transparent liquid crystal and show, this display mode does not need backlight circuit that light source is provided, and only utilizes the natural daylight just can display frame, and the brightness that its brightness that presents is compared when adopting backlight circuit wants high a lot, has also reduced energy consumption simultaneously.
In the present embodiment, outside input power is after power supply processing module 8 is processed, and the direct voltage of exportable 12V, 5V and 3V is drive plate 7 and power amplifier 9 power supplies.
After LCD projecting apparatus disclosed in the utility model, its drive plate are processed outer video signal, be shown on the transparent liquid crystal screen, this transparent liquid crystal screen does not need lighting of backlight circuit, only just can display frame by natural daylight.Therefore, the LCD projecting apparatus of this structure has that brightness is high, a good stability, low power consumption and other advantages, has wide market prospects in LCD projector equipment field.
The above is the utility model preferred embodiment, is not limited to the utility model, all modifications of making in technical scope of the present utility model, is equal to and replaces or improvement etc., all should be included in the scope that the utility model protects.
