Embodiment Construction

[0020] Embodiments of the present invention will be described with reference to the drawings.

[0021] [Overall structure of display device]

[0022] figure 1 with figure 2 A structural example of a display device according to an embodiment of the present invention is shown. The display device includes a display unit 1 , a lenticular lens 2 as a parallax separation device (separation unit), and a backlight 3 .

[0023] The display unit 1 includes a two-dimensional transmissive display device, for example, the two-dimensional transmissive display device is a transmissive liquid crystal display panel. A plurality of pixels (or sub-pixels) 1A are two-dimensionally arranged on the display screen of the display unit 1 . A plurality of viewpoint images are time-divided and displayed N (an integer equal to or greater than 2) times on the display screen of the display unit 1 .

[0024] exist figure 1 with figure 2 In the example of , the first to sixth viewpoint images are di...

Abstract

The present invention relates to display devices. The display device includes: a display unit that time-divisionally displays a plurality of viewpoint images in N times, where N is an integer greater than or equal to 2; a backlight that irradiates image display light to the display unit; The M viewpoint images displayed in the display unit are separated, and M is an integer greater than or equal to 2. The backlight can switch and control the light emitting direction among N directions, and can time-divisionally switch and control the light emitting direction in synchronization with the timing of the time-division display performed by the display unit.

Description

technical field [0001] The present invention relates to a display device that performs stereoscopic display of a naked-eye method by using a parallax separation device such as a parallax barrier. Background technique [0002] There are two types of stereoscopic display methods: a glasses method that uses glasses for stereoscopic viewing, and a naked-eye method that enables stereoscopic viewing with naked eyes without special glasses for stereoscopic viewing. As a general glasses method, there is a shutter glasses method using shutter glasses having a left-eye shutter and a right-eye shutter. In the shutter glasses method, left-eye and right-eye parallax images are alternately displayed in a frame-continuous manner on a two-dimensional display panel at high speed. The left-eye shutter and the right-eye shutter are switched alternately at the moment when the left-eye and right-eye parallax images are displayed, so that the left-eye and right-eye parallax images enter the obse...
