Problems solved by technology

[0009] However, the above-mentioned multi-view display device has such a problem: in the case of displaying images with different viewing directions at the same time, in order to make an observer only watch one image clearly, it needs to be determined from the distance from the above-mentioned display device and However, since the range is narrow, when observing from a slightly different area, a part of one image is superimposed on another image, forming a so-called double image. image
In particular, even when only one observer exists, a double image will be generated when two different images are displayed. Therefore, it is necessary to determine the observation position of the image in an extremely narrow range. Very unsatisfactory for observers
[0010] In addition, the above-mentioned multi-view display device needs to have the number of pixels for displaying the amount of source signals corresponding to the number of viewing directions in order to simultaneously display different images on one screen according to the viewing directions. In order to incre

Abstract

For a multi-view display device 325 in which a pixel group constituting a screen is distributively arranged to a first pixel group and a second pixel group and different images are simultaneously displayed in two directions by individually driving video images on the basis of video signals with different sources, there are provided: a first driving mode control means 347 for individually driving both pixel groups on the basis of video signals with different sources; second driving mode control means 346, 349 for driving either pixel group so that a video grade to be displayed by either pixel group is enhanced; and a mode switching means 348 for performing switching control of the first driving mode control means and the second driving mode control means.

Description

technical field [0001] The present invention relates to a multi-view display device capable of providing independent and different information to a plurality of users substantially simultaneously on a single screen. Background technique [0002] The development of the main displays so far has been carried out in such a way that the observer can view the display with the same good image quality regardless of which direction the observer looks at it, or in a manner that a plurality of observers can simultaneously obtain the same information. optimized. However, there are many uses where each observer wishes to view different information from the same display. For example, in a car, there may be situations where the driver wants to watch satellite navigation data, while the passenger next to him wants to watch images from the car DVD, TV tuner, etc. In such an example, when two monitors are used, there is a problem of taking up an extra space and increasing the cost.
