Embodiment 1

[0057] Embodiment 1, the light source is a monochromatic light source of at least three colors

[0058] Take a monochromatic light source with three colors as an example, such as Figure 5 As shown, the light source 170 includes a first light source 171, a second light source 172 and a third light source 173, wherein the first light source 171 is a first monochromatic light source, and the second light source 172 is a second monochromatic light source , the third light source 173 is a third monochromatic light source.

[0059] The light guide plate 110 is a three-layer light guide plate, the light incident side of the first layer of light guide plate 111 is provided with a first light source 171, the light incident side of the second layer of light guide plate 112 is provided with a second light source 172, the third layer of light guide plate The light incident side of 113 is provided with a third light source 173 .

[0060] In this embodiment, the first light source 171 , ...

Embodiment 2

[0066] Embodiment 2, the light source is a white light source

[0067] Such as Figure 8 As shown, the light source 170 includes a first light source 171, a second light source 172 and a third light source 173, wherein the first light source 171, the second light source 172 and the third light source 173 are all white light (W )light source.

[0068]The light guide plate 110 is a three-layer light guide plate, the light incident side of the first layer of light guide plate 111 is provided with a first light source 171, the light incident side of the second layer of light guide plate 112 is provided with a second light source 172, the third layer of light guide plate The light incident side of 113 is provided with a third light source 173 .

[0069] Such as Figure 8 with Figure 9 As shown, different light-emitting patterns 160 are provided on each layer of light guide plates, and the first light-emitting patterns 161, second light-emitting patterns 161, and The light-emi...

Abstract

The invention discloses a display device and a display method. The display device includes: a light source, a light guide plate, and a liquid crystal panel, and the liquid crystal panel includes a first substrate and a second substrate in a box, and the first substrate and the second substrate are A liquid crystal layer is arranged between the two substrates; a light-emitting pattern is arranged on the light guide plate, and the incident light of the light source passes through the light-emitting pattern of the light guide plate to form monochromatic light of at least three colors; the light source is turned on time-sharing , allowing the monochromatic light of the at least three colors to irradiate the same sub-pixel electrodes on the first substrate in time division in each frame time to form reflected light, and the reflected light is modulated by the liquid crystal layer displayed afterwards. In the embodiment of the present invention, since the light source is turned on in time-division, the monochromatic light of at least three colors is irradiated on the same sub-pixel electrode on the first substrate in time-division within each frame time, that is, each sub-pixel The dot position can display at least three colors of monochromatic light, thereby improving the PPI of the display device.

Description

technical field [0001] The present application relates to but not limited to the field of display technology, especially a display device and a display method. Background technique [0002] With the development and upgrading of display technologies, various types of displays appear, including, for example, liquid crystal displays (Liquid Crystal Display, LCD for short). In a display, an optical processing to form a display device with various colors is an important part thereof. [0003] LCD displays generally include reflective LCD displays and transmissive LCD displays. Such as figure 1 As shown, it is a schematic structural diagram of a display device in the prior art. The display device is a reflective display device, and its basic structure generally includes: a first substrate and a second substrate for the box, and a polarizer (Polarizer, referred to as : POL) and light guide panel (Light GuidePanel, referred to as: LGP). Wherein, the first substrate may be a thin...
