Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation, but be not limited to this.
As shown in Figure 1, the projector of a kind of high pixel of the utility model, comprise casing 1, and be located at lighting apparatus component 2 and circuit board 3 in the casing 1, lighting apparatus component 2 comprises projection light source 21, LCD transparent display board 22 and imaging lens set 23, the video processing module 32 that circuit board 4 is provided with microcontroller 31 and connects with microcontroller 31, video processing module 32 connects with LCD transparent display board 22, LCD transparent display board 22 is for being provided with the selectable maximum LCD panel of using pixel and common use pixel at least, the maximum pixel of video processing module 32 is identical with the maximum pixel of LCD transparent display board 22, microcontroller 31 is provided with at least to be respectively applied for and produces maximum two groups of pixel control signals using pixel and common use pixel, it is the selector switch that microcontroller is provided with two groups of pixel control signals that can produce maximum use pixel (being 1024 pixels * 768 pixels in the present embodiment) and common use pixel (being 800 pixels * 600 pixels in the present embodiment) at least, casing is provided with the selector switch 30 that is used to select to use pixel that connects with the LCD transparent display board (i.e. this selector switch can produce at least maximum to use pixel be that 1024 pixels * 768 pixels and common use pixel are two groups of pixel control signals of 800 pixels * 600 pixels), the modification that this selector switch 30 is mainly used in pixel produces corresponding electric signal, comprising the actual pixels of output from video processing module 32, the real work pixel of LCD transparent display board 22 and the size of projection light source 21.Projection light source 21 is the adjustable light source of led light source.Circuit board 3 also is provided with storer 33, USB communication module 34, the ethernet communication module 35 that connects with microcontroller 31.Video processing module 32 is provided with also that VGA input connects 321, VGA output connects 322, AV input interface 323 and AV output interface 324.Circuit board 3 also is provided with the audio processing modules 36 that connects with microcontroller 31.Audio processing modules 36 be provided with audio frequency input connect 361 and audio frequency output connect 362.
