Embodiment 1

[0038] Such as figure 1 , 4 As shown, this embodiment provides a backlight module, including a light generation unit 100 and a light emission control unit 200; wherein, the light generation unit 100 can generate two layers of point light source arrays that are opposite and arranged at intervals, wherein the first layer Each point light source of the point light source array 101 and each point light source of the second layer point light source array 102 are arranged alternately; the light emission control unit 200 can control the light generation unit 100 to generate the first layer point light source array 101 and the second layer Point light source array 102 .

[0039] The backlight module of this embodiment is applied to a display device. When a certain frame is displayed, the light-emitting unit of the backlight module generates a first-layer point light source array 101 at the first moment through the control of the light-emitting control unit 200. , so as to display a ...

Embodiment 2

[0047] Such as Figure 4 As shown, this embodiment provides a display device, which includes the backlight module described in Embodiment 1 and the picture element 400 disposed on the light-emitting surface of the backlight module. The display device may be any product or component with a display function such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0048] Because the display device of this embodiment includes the backlight module described in Embodiment 1, it can realize 3D display, and can also realize 2D display, and the depth of field of the formed 3D picture is obviously enhanced, and the structure of the display device is more compact, and the preparation Simple process.

[0049] Preferably, the display device further includes a PDLC (polymer dispersed liquid crystal) optical switch unit, and the PDLC optical switch unit 300 is arranged between the backlight module and the im...

Embodiment 3

[0052] This embodiment provides a display method of a display device, which includes: controlling the light generating unit to generate at least two opposing point light source arrays in turn by the light emitting control unit, wherein each layer of the point light source array includes a plurality of point light source arrays Each point light source layer of each point light source array is arranged at intervals along the light emitting direction, and the projections of each point light source on a plane perpendicular to the light emitting direction are arranged alternately.

[0053] It should be noted that the display device in this embodiment may be the display device described in Embodiment 2.

[0054] Since the display method of this embodiment can control the light generation unit to generate at least two opposing point light source arrays in turn through the light control unit, the display method of this embodiment can realize the display of 3D images.

[0055] Preferab...

Abstract

A backlight module, a display device and a displaying method of the backlight module are disclosed. The backlight module includes a light generation unit and a light emitting control unit. The light generation unit is configured to generate at least two light spot arrays that are spaced from each other, each light spot array includes a plurality of light spots, and projections of the respective light spots on a plane that is vertical to a light emitting direction of the light generation unit are staggered from each other; the light emitting control unit is configured to control the light generation unit to alternatively generate the at least two light spot arrays. The backlight module can be used for 3D displaying, and the depth of field in the displayed image is increased, and the structure of the backlight module is more compact.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a backlight module, a display device and a display method thereof. Background technique [0002] Integrated imaging stereoscopic display technology is a 3D stereoscopic display technology that does not require any visual aids. This technology has the characteristics of stereoscopic viewing with naked eyes, its recording and display process is simple, and it can display full parallax and true stereoscopic display without stereoscopic viewing fatigue. It is one of the hot spots in 3D stereoscopic display technology at present. [0003] The traditional way to achieve integrated imaging is to use microlens arrays or use pinhole arrays, and point light source arrays. Among them, when the pinhole array is used to realize integrated imaging, the light utilization rate is very low due to the small aperture of the pinhole array, and increasing the aperture will affect the de...
