Show that module 100 is contained in housing 201, for showing image and can be for the angles of display of beholder's position adjustments display 200 and the homogeneity of brightness.Show that module 100 comprises luminescence unit 50, micro-reflector element 70 and micro-control unit 90(Micro Control Unit, MCU).Image unit 205, range cells 207, photometry unit 209, luminescence unit 50 and micro-reflector element 70 all are electrically connected with micro-control unit 90.

Image unit 205 is for obtaining the image data in its field range, and the image data obtained is sent to micro-control unit 90.In present embodiment, image unit 205 is an imageing sensor.

Range cells 207 is for the distance of the eyes position range display 200 that measures the beholder, and the range data of measurement is sent in micro-control unit 90.In present embodiment, range cells 207 is a distance measuring sensor.

Photometry unit 209 is for the light luminance in its week side ring border of sensor display 200 use procedure, and the light luminance information sensed is sent to micro-control unit 90.In present embodiment, photometry unit 209 is a photometry sensor.

Luminescence unit 50 is for sending the light with color and certain brightness, and it comprises some light emitting diode 51(Light Emitting Diode, LED) and LED driving chip 53(LED IC).See also Fig. 3, in present embodiment, some LED51 comprise red diodes, green diode and blue light diode.Red diodes, green diode and blue light diode order are successively arranged.Each LED51 comprises base station 517 and is arranged at the light-emitting area 519 on base station 517.LED drives chip 53 and micro-control unit 90 and some LED51 to be electrically connected, with driving LED 51 work.

Micro-reflector element 70 is for changing the transmission direction of LED51 output light.Each micro-reflector element 70 comprises that plural micro-reflector 71 and a micro-reflection drive chip 73(MEMS IC).Each micro-reflector 71(MEMS mirror) include two support columns 713 and an eyeglass 715.Two support columns 713 are installed on base station 517, and relatively are positioned at light-emitting area 519 both sides.Eyeglass 715 is installed in support column 713 rotationally away from base station 517 1 ends, and aims at light-emitting area 519.Micro-reflection drives chip 73 and micro-control unit 90 and some micro-reflectors 71 to be electrically connected.Micro-reflection drives chip 73 in order to drive eyeglass 715 to rotate around support column 713, thereby the light that LED51 light is sent reflexes in eyes with proper angle.

Micro-control unit 90 comprises identification module 93, reflection processing module 95 and Graphics Processing module 97.Identification module 93 is electrically connected with image unit 205 and range cells 207, in order to receive image data that image unit 205 obtains, according to this image data judge whether to obtain in situation that the beholder exists, exists in the beholder these beholder's eyes positional information, store this eye position information and send distance measuring instruction to range cells 207.Be appreciated that the image data that identification module 93 can obtain according to image unit 205, directly obtain the positional information of beholder's eyes.

Reflection processing module 95 is electrically connected with range cells 207 and micro-reflector element 70, measure the range data of the beholder's eyes position range display arrived for receiving range cells 207, and calculate the required rotational angle around support column 713 of each eyeglass 715 according to this range data, and these data are passed to micro-reflection driving chip 73.

Graphics Processing module 97 is electrically connected with photometry unit 209 and luminescence unit 50, for receiving the light luminance information in 200 weeks side ring borders of display that photometry unit 209 senses, and according to the ratio of display 200 weeks side ring environmental lights brightness and LED51 display brightness, determine the brightness of the required demonstration of LED51, and data are passed to LED driving chip 53.

When display 200 is used, if the beholder is positioned at screen 203 Yi Ge positions, the place ahead, image unit 205 obtains the image in its field range, and the image data obtained is sent in identification module 93.If whether identification module 93 has the beholder to exist according to this image data judgement, as existed, by continuing, obtain the positional information of these beholder's eyes and send distance measuring instruction to range cells 207.Range cells 207 measures the distance of the relative display 200 of eyes, and the range data transmission of obtaining is fed back to reflection processing module 95.Reflection processing module 95 is carried out computing according to this range data, draws the required rotational angle around support column 713 of each eyeglass 715, and this angle-data is passed to micro-reflection driving chip 73.Micro-reflection drives chip 73 to receive and controls eyeglass 715 according to this angle-data and carry out the rotation of certain angle around support column 713, by the light reflection (as shown in Figure 4) in eyes of LED51 light output.Simultaneously, photometry unit 209 obtains 200 weeks side ring environmental light monochrome informations of display, and is transferred to Graphics Processing module 97.Graphics Processing module 97 is carried out computing according to the proportionate relationship of the brightness of all side ring environmental lights and display 200 display brightness, determines the required display brightness of LED51, and sends data to LED driving chip 53.LED drives chip 53 to control the brightness that LED51 adjusts output light.

Can understand, can omit photometry unit 209, and directly by micro-reflector element 70 by light reflection in eyes, thereby realize that the beholder feels that display 200 display brightness are comparatively even.

Can understand, 71 need of micro-reflector meet the light reflection that light-emitting area 519 is sent and get final product to eyes, as the base station of LED51 517 is movably set on a pedestal (not shown), micro-reflector 71 relative luminous faces 519 are directly fixed on the similar objects such as a substrate (not shown) or fixed bar, and now reflect processing module 95, with luminescence unit 50, be electrically connected, the range data computing that reflection processing module 95 measures according to range cells 207 draws the angle of each base station 517 required rotations and the angle of the required activity of each LED51 is sent to LED and drives on chip 53, LED drives chip 53 to drive base station 517 to turn an angle so that the light that light-emitting area 519 is sent reflexes in eyes through micro-reflector 71.Accordingly, micro-reflector element 70 can be economized reflection slightly and drive chip 73, and micro-reflector 71 can omit support column 713.

Display 200 provided by the invention, its image unit 205 can obtain image within the vision and data can be sent to identification module 93 identification eye positions; Range cells 207 measures eyes and is sent to reflection processing module 95 from the distance of display 200 and by range data.Display 200 is according to the eyes position, make micro-reflector 71 by the light reflection of LED51 output in eyes.Because the beholder is not all incided in beholder's eyes over against the light of the LED output of light-emitting diode display part, the beholder can not feel that other position brightness is dulller, and the colourity that also sensation shows is comparatively even, has promoted the experience of watching.In addition, show that module 100 also is provided with photometry unit 209, it can regulate the brightness of LED51 output light according to the brightness of 200 weeks side ring environmental lights of display, improves the comfort level that the beholder watches.

Be understandable that, those skilled in the art also can do other variation in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
