Problems solved by technology

The space sequential display device uses a parallax barrier that does not operate over time to allow the left and right eyes to see different groups of pixels, and these two groups of pixels are given signals to the left and right eyes respectively, so that the two eyes can see different images; the disadvantage is that the resolution rate will drop

Embodiment 1

[0051] Please refer to Figure 1A , which is a schematic diagram of the display device of the present invention. The display device includes: a display unit 1 , a modulation unit 2 , and a backlight unit 3 , and the modulation unit 2 is arranged between the display unit 1 and the backlight unit 3 . The display unit 1 includes in sequence: a first polarizer 11, a first substrate 12, a pixel layer 13, a second substrate 14, and a second polarizer 15; the modulation unit 2 includes in sequence: a third substrate 21, a first conductive layer 22, liquid crystal layer 23, second conductive layer 24, fourth substrate 25, and barrier layer 6;

[0052]In the present invention, the display unit 1 is not limited, for example, it may be a common liquid crystal display unit (LCD) or an organic light emitting diode display unit (OLED). The pixel layer 13 includes a plurality of pixel units 131. When the display unit 1 is a liquid crystal display unit, the plurality of pixel units 131 inclu...

Embodiment 2

[0067] A detailed description of the backlight unit in the display device of the present invention is as follows. See Figure 2A , Figure 2B , which are two implementations in which multiple stripe patterns 5 and reflective layers 71 and 72 are provided on the backlight unit 3 . Wherein, the backlight unit 3 includes a light-emitting element 31 and a light guide plate 32, the light-emitting element 31 is arranged on both sides (light-incident surfaces) of the light-guide plate 32, and the light-guide plate has a first surface 321 (light-emitting surface) and an opposite second surface 322 (bottom surface), and the first surface 321 is adjacent to the modulation unit (not shown), and the second surface 322 of the light guide plate 32 is provided with a plurality of stripe patterns 5; as Figure 2A As shown, the reflective layer 71 can be disposed on the second surface 322 and cover the second surface 322 and the plurality of stripe patterns 5; or as Figure 2B As shown, the...

Embodiment 3

[0071] See image 3 , which is a schematic diagram of a display device in another embodiment of the present invention; in this embodiment, the display unit 1 is combined with the modulation unit 2 so that a substrate can be omitted. In detail, the display unit 1 includes in sequence: a first polarizer 11 , the first substrate 12, the pixel layer 13, and the second substrate 14, the modulation unit 2 includes in sequence: a first conductive layer 22, a liquid crystal layer 23, a second conductive layer 24, a fourth substrate 25, and a second polarizer Component 15; accordingly, the display unit 1 and the modulation unit 2 share the second substrate 14, and the third substrate 21 included in the modulation unit 2 in Embodiment 1 can be omitted, reducing the weight of the device and the cost of the substrate. In addition, the backlight unit 3 in this embodiment and Figure 2A Same, no longer repeat the description here.

[0072] In this embodiment, the display unit 1 is a liqui...

Abstract

The invention relates to a display device. The display device comprises a display unit provided with a picture element layer; a backlight unit; and a modulation unit which is arranged between the display unit and the backlight unit and comprises a liquid crystal layer, wherein the liquid crystal layer comprises a polymer dispersed liquid crystal (PDLC) or a polymer stabilized liquid crystal (PSLC).

Description

technical field [0001] The present invention relates to a display device, in particular to a display device capable of switching two-dimensional (2D) and three-dimensional (3D) images. Background technique [0002] Human beings perceive the image of the real world through the outlook seen by the eyes. The human brain will further form a so-called 3-dimensional (3-dimension, 3D) image according to the spatial distance difference between two perspectives from different angles seen by the eyes. Generally speaking, a 3D display device is a display device that simulates the field of view of human eyes at different angles, so that the observer can perceive a 3D image when watching a 2D display image. [0003] The current 3D display devices are mainly divided into two categories, which are auto-stereoscopic display devices (Auto-stereoscopic display) and non-auto-stereoscopic display devices (Stereoscopic display). Users of autostereoscopic image display devices can see three-dim...
