This is looked squarely display system and also comprises light intensity sensor 106 and system control unit 101, and light intensity sensor 106 is connected with system control unit 101, for surveying the light intensity of surrounding environment, and light intensity data is fed back to system control unit 101.System control unit 101 is connected with indicative control unit 102, for coordinating the collaborative work of indicative control unit 102 and light intensity sensor 106, system control unit 101 sends the signal of adjusting flat-panel display device 100 output brightness to indicative control unit 102 according to the light intensity data receiving.Meanwhile, system control unit 101 is also responsible for carrying out data communication with the external world.For example, when the strength ratio that detects surrounding environment light when light intensity sensor 106 is weak, the signal that system control unit 101 feeds back according to light intensity sensor 106, send instruction to backlight control module 103, turn down the light output of backlight 105, thereby turn down the brightness of display frame, protected observer's eyesight; When light intensity sensor 106 detects surrounding environment light when more intense, the signal that system control unit 101 feeds back according to light intensity sensor 106, heightens the light output of backlight 105, makes the brightness of display frame brightness higher than background frame, to ensure the clear of picture.
As shown in Figure 2, be another preferred embodiment of the utility model, look squarely display system and comprise flat-panel display device 100, system control unit 101, indicative control unit 102, light intensity sensor 106 and reflection type polarization device 107.Flat-panel display device 100 is for being pasted with the organic light emitting display 202 of circular polarizing disk 201, the exit facet that the line light polarizing film of circular polarizing disk 201 is linearly polarized light, as shown in Figure 4, this organic light emitting display 202 that is pasted with circular polarizing disk 201 comprises substrate 401, metal electrode 402, organic luminous layer 403, transparency electrode 404, transparency carrier 405, one-quarter wavelength retardation film 406 and line polaroid 407, wherein substrate 401, metal electrode 402, organic luminous layer 403, transparency electrode 404, transparency carrier 405 forms organic light emitting display 202, one-quarter wavelength retardation film 406 and line polaroid 407 form circular polarizing disk 201.Circular polarizing disk 201 is attached at the exiting surface of organic light emitting display 202, the light being sent by organic light emitting display 202 is without polarizability, after the one-quarter wavelength retardation film 406 in circular polarizing disk 201, still without polarizability, after crossing line polaroid 407, become linearly polarized photon.
In organic light emitting display technology; the metal electrode 402 of organic light emitting display 202 bottoms has very high reflectivity conventionally; therefore in the time that extraneous light is more intense; can cause seeing clearly the shown picture of organic light emitting display 202; in order to address this problem; conventionally attach one deck circular polarizing disk on organic light emitting display surface; wherein the one-quarter wavelength retardation film of circular polarizing disk attaches mutually with organic light emitting display, and the line polarizer sheet sticking in circular polarizing disk is in the outside surface of one-quarter wavelength retardation film.In the time that ambient lighting is mapped to the organic light emitting display surface of posting circular polarizing disk, first penetration line polaroid, light becomes linearly polarized light, then becomes circularly polarized light after one-quarter wavelength retardation film; Circularly polarized light arrives metal electrode layer after each layer, and at surface of metal electrode generation mirror-reflection, now circularly polarized light will become sense of rotation and the front contrary circularly polarized light of reflection; When reflection ray is by after one-quarter wavelength retardation film, will be converted into linearly polarized light, its polarization direction is just vertical with the polarization direction of line polaroid, therefore cannot see through linear polarizer.Therefore, use circular polarizing disk effectively to solve the metal electrode of organic light emitting display to the reflection problems of ambient light, exactly because also attached circular polarizing disk, the light sending from organic light emitting display is also converted into linearly polarized light, thereby has met this and look squarely the requirement of display system.
Combine with above-mentioned each embodiment, reflection type polarization device 107 is the reflection type polarization device based on multilayer dielectric film, reflection type polarization device 107 can be attached at shield glass inside surface, and the angle between reflection type polarization device 107 and flat-panel display device 100 is 45 degree, the number of degrees of this angle do not require very accurate, can in the positive and negative 5 degree left and right of 45 degree.This reflection type polarization device 107 can see through the light of automobile external 50% left and right, and can reflector plate display device 100 100% light nearly, its balance reflectivity and the light transmission of light source, reach higher light source utilization factor.LCDs 104 be placed horizontally at reflection type polarization device 107 under, and ensure the light transmission shaft direction of its surperficial polaroid 311 of positive apparent time and the light transmission shaft direction of reflection type polarization device 107 vertical.
In the time that reality is used, the light that display system enters into driver's eye of looking squarely based on polarized light is divided into three parts, and Part I comes from flat-panel display device 100 and after the reflection of reflection type polarization device 107, incides the light in human eye; Part II is extraneous light after the body surface reflection beyond flat-panel display device 100 viewing areas, then enters the light of human eye 108 through 107 reflections of reflection type polarization device; Part III is the light that car external environment light enters into human eye 108 after 107 transmissions of reflection type polarization device.
For the light of Part I, the light seeing through after flat-panel display device 100 is linearly polarized light, during through described reflection type polarization device 107 surface, because polarization direction is vertical with the light transmission shaft direction of reflection type polarization device 107, light will almost all be reflected, and enters into driver's eye.Reflection type polarization device 107 approaches 100% for the reflectivity of the polarization direction linearly polarized light vertical with himself light transmission shaft direction, and as shown in Figure 5, therefore the emergent ray of liquid crystal display device is substantially all reflected onto in driver's eye its reflectance spectrum.Under normal circumstances, natural light through reflection after by the characteristic with partial line polarization, its polarization direction is horizontal direction, therefore the absorption axes of polarisation sunglasses is designed to horizontal direction, corresponding light transmission shaft is vertical direction, for absorbing the linearly polarized light of most reflection ray, thereby filter out the multiple interference light in driver's eye, ensure driving safety.That is, should be based on the looking squarely display system and can use together in conjunction with polarisation sunglasses in use of polarized light, the efficiency of light energy utilization of light source can be better.Certainly, this looks squarely display system can not affect it yet and use and relevant function in the situation that there is no polarized sunglasses.Consider the compatibility with polarized sunglasses, in the present embodiment, light transmission shaft direction at positive apparent time reflection type polarizer part 107 is horizontal direction, the surperficial polaroid light transmission shaft direction of liquid crystal display device 104 is vertical direction, and the light therefore sending from flat-panel display device 100 will be reflected formula polarizer 107 and all reflect.
For Part II light, in the time that solar irradiation is mapped to the body surface beyond flat-panel display device 100 viewing areas, its reflection ray will be with partial poolarized light, and polarization direction is horizontal direction, therefore when through reflection type polarization device 107, major part is seen through and is not reflected.Because for the polarization angle linearly polarized light identical with reflection type polarization device 107, its reflectivity is about 3% left and right, and reflectance spectrum as shown in Figure 6.Therefore the light that the object beyond liquid crystal display device viewing area reflects will significantly not reflected in reflection type polarization device 107, has so just improved demonstration image and the contrast difference of object around, and display frame is more clear.
For Part III light, light into the car from vehicle window, when through wavelength selectivity reflection device reflection type polarization device 107, only there is the light transmission reflection type polarization device 107 of 45% left and right, reduce to a certain extent the interference to reflected image, contributed to improve the contrast of reflected image and the outer background of car.Reflection type polarization device 107 to natural light see through spectrum as shown in Figure 7, in visible light wave range scope iuuminting rate in 46% left and right.If driver wears polarisation sunglasses, because of the polarization direction of polarisation sunglasses vertical with the polarization direction of reflection type polarization device 107, therefore while passing through polarisation sunglasses again after car UV light passes reflection type polarization device 107, will all be filtered, only there is the light on liquid crystal display device surface to enter in driver's eye, can filter the interference of the outer background light of car to reflected image completely, therefore described looking squarely the display system polarisation sunglasses of arranging in pairs or groups in use and will further improve the imaging effect of originally looking squarely display system based on polarized light.
Described based on polarized light look squarely the organic light emitting display 202 of circular polarizing disk 201 that display system adopts liquid crystal display device 104 or be pasted with antireflection as flat-panel display device 100, use the reflection device of reflection type polarization device as image.The reflectivity that polarization direction is seen through to the linearly polarized light of axle perpendicular to it due to reflective linear polarization device 107 approaches 100%, make the linearly polarized light sending from display device can be reflected the reflection of formula polarizer, and be only 50% left and right for the reflectivity of nonpolarized light, therefore the reflectivity of the image beyond viewing area on reflection type polarization device can reduce greatly, thereby reflected picture is separated object areas in addition in brightness with picture, improve the brightness of reflected picture and the contrast with background, thereby promote imaging effect.Meanwhile, this is looked squarely display system and also has the features such as simple in structure, visual range is wide.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
