According to above-mentioned display device 301,, provide following advantageous effects because liquid crystal printing opacity/shadow shield is adjusted the emergent light hidden position that signal changes shadow shield 308 according to the visual angle that inputs to it.That is, because described shading position not only can be moved as a whole, and can also be with the meticulous variation of various patterns, thereby, can be that the best shading position that signals obtain shadow shields 308 is adjusted at various visual angles.Because can be by realizing the visual angle adjustment according to adjust the shading position of shadow shield 308 that signal change be placed on the place ahead of LCD panel 306 via the visual angle of input media input, therefore, can be according to various situations, for example, traveling state of vehicle automatically carries out described adjustment.
Because it is the signal of indication for the adjusted value of all directions of output different images that visual angle or visual range are adjusted signal, can be for adjusting independently at each image of different directions output.This also may reduce crosstalks.Further, owing to be used for the visual angle or presetter device (presetting part) that the scope of watching is adjusted for display device 301 has been equipped with, can be fast and easily adjust described visual angle and watch scope.In other words, in case adjusted value is stored in the storer 305, just can obtain the emergent light hidden position of shadow shield 308 uniquely according to described adjusted value.Preset, can adjust described visual angle and visual range efficiently and easily.
Because the visual angle in storer 305 has been stored a plurality of adjusted values with watching in the scope adjusted value storage area for each direction, therefore, optimal viewing angle can be set for the beholder who is positioned at all directions and watch scope.So a plurality of beholders that are positioned at a plurality of different directions can clearly watch the different images of preparing into each beholder.When the visual angle in storer 305 with watch in the scope adjusted value storage area when having stored adjusted value, for the beholder who is positioned at each specific direction is provided with described visual angle and watches scope for all directions.According to display device 301, can utilize liquid crystal cell to realize described printing opacity/shading control.So, and compare by utilizing drive source to drive the prior art that described slit carries out described control, not only can simplified structure, can also dwindle the size of described display device.
By operation touch pad 307, the beholder can the described visual angle of manual adjustment or is watched scope.Because show described adjustment image between the adjustment period of the visual angle, the beholder can watch the adjustment image when adjusting described visual angle exactly easily.Further, owing to illustrate at the visual angle or between watch scope the adjustment period. the image of described adjusted value, described beholder can be when switch be adjusted at the described visual angle of operation the inspection adjusted value.Therefore, the beholder can easily store described adjusted value, the repeatability that this helps to improve the visual angle or watches scope to adjust.By when adjusting the visual angle or watching scope, reducing visual range, can adjust the visual angle or watch scope in high accuracy ground.
According to display device 301, by input traveling state of vehicle signal, can change the shading position of shadow shield 308, thus the coupling traveling state of vehicle, and therefore, can realize suitable visual angle.For example, the beholder does not need moving-head to wait to offset centrifugal force or the inertial force that occurs owing to travel conditions.This helps to alleviate beholder's somatotonia.Therefore, the beholder can clearly cosily watch desirable image, and can not be subjected to the influence of traveling state of vehicle.Further, when input temp signal during with the environment temperature of indicated number device 301, the distortion that can occur owing to variation of ambient temperature to the shading position compensation of shadow shield 308.The accuracy that this has improved the visual angle and has watched scope to adjust.Further, when utilizing CCD to make a video recording the position signalling of first-class input indication beholder position, may discern described beholder's position, and can adjust described visual angle and watch scope in pin-point accuracy ground, thus coupling beholder's position.In the present invention, term " image " comprises rest image or moving image at least.
As optional embodiment of the present invention, a kind of input media is provided, be used to import the eye position signal of indication beholder's left eye and right eye position, and described liquid crystal printing opacity/shadow shield can be controlled to change the shading position of shadow shield 308, thereby makes the beholder to watch different images with its left eye and right eye respectively.According to this structure, because the beholder can watch different images with its left eye and right eye respectively, the beholder can watch stereo-picture.Further, dynamically do not change the shading position of described shading light part, can fix the setting of described shading light part, thereby make that for example, when installing according to vehicle (when dispatching from the factory), the left and right sides is asymmetric.The invention is not restricted to automobile and use, it also is applicable to domestic. applications.
