Problems solved by technology

The fingerprint identification module is usually opaque. After the cover plate is assembled with the display panel, the opaque fingerprint identification module is located above the display panel. The fingerprint identification module can only be located in the non-display area of ​​the liquid crystal display device, resulting in no Further increasing the proportion occupied by the display area of ​​the liquid crystal display device cannot effectively utilize the actual space of the liquid crystal display device

Embodiment 1

[0048] see figure 1 , the liquid crystal display device 100 of the first embodiment defines a display area 101, and a fingerprint sensing area 103 is arranged in the display area 101, such as figure 1 The area marked by the dotted box. In this embodiment, the liquid crystal display device 100 is a mobile phone.

[0049] Please also refer to figure 2 The liquid crystal display device 100 includes a backlight module 30 and a display panel 10 stacked on the backlight module 30 , and also includes a fingerprint sensing module 50 disposed in the backlight module 30 . The backlight module 30 is used to project light to the display panel 10 , the display panel 10 displays images by the light from the backlight module 30 , and the fingerprint sensing module 50 is used for fingerprint identification. Since the fingerprint sensing module 50 is arranged in the backlight module 30 below the display panel 10, the fingerprint sensing module 50 will not interfere with the display of the ...

Embodiment 2

[0057] Please also refer to figure 1 and Figure 4 , the liquid crystal display device 200 of the second embodiment, which is basically the same as the liquid crystal display device 100 of the first embodiment, also includes a stacked display panel 10 and a backlight module 30 and a fingerprint sensor arranged in the backlight module 30 Module 50.

[0058] The difference between the liquid crystal display device 200 of the second embodiment and the liquid crystal display device 100 of the first embodiment is that in this embodiment, the fingerprint sensing module 50 is at least translucent, such as transparent or translucent ;Such as Figure 4 As shown, there is no accommodating hole in the backlight module 30 for installing the fingerprint sensing module 50 , and the fingerprint sensing module 50 is directly disposed between the diffusion sheet 35 of the backlight module 30 and the LED 33 .

[0059] The side of the diffusion sheet 35 away from the LED33 is also provided wi...

Embodiment 3

[0063] see Figure 5 The liquid crystal display device 300 of the third embodiment defines a display area 101, and the display area 101 is also a fingerprint sensing area 103. The display area 101 and the fingerprint sensing area 103 are basically the same size, that is, the liquid crystal display device 300 can support Full screen fingerprint recognition.

[0064] The liquid crystal display device 300 of the third embodiment is basically the same as the liquid crystal display device 100 of the first embodiment, and also includes a stacked display panel 10 and a backlight module 30, and also includes a fingerprint sensing module arranged in the backlight module 30 Group 50, such as Figure 6 shown.

[0065] The difference between the liquid crystal display device 300 of the third embodiment and the liquid crystal display device 100 of the first embodiment is: there is no accommodating hole in the backlight module 30 for installing the fingerprint sensing module 50, such as ...

Abstract

A liquid crystal display device is defined with a display area and comprises a backlight module, a display panel stacked on the backlight module and a fingerprint sensing module arranged in the backlight module, and the fingerprint sensing module is located in the display area so as to form a fingerprint sensing area in the display area. According to the invention, the fingerprint sensing module is arranged in the backlight module, display of the display panel is not affected, so that the fingerprint sensing area is formed in the display area, a wide non-display area does not need to be arranged to arrange the fingerprint sensing module, and the proportion occupied by the display area of the liquid crystal display device can be increased.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device with a fingerprint identification module. Background technique [0002] In an existing liquid crystal display device, such as a mobile phone, a fingerprint identification module is combined with a cover to form an external fingerprint identification module. The fingerprint identification module is usually opaque. After the cover plate is assembled with the display panel, the opaque fingerprint identification module is located above the display panel. The fingerprint identification module can only be located in the non-display area of ​​the liquid crystal display device, resulting in no Further increasing the proportion occupied by the display area of ​​the liquid crystal display device cannot effectively utilize the actual space of the whole liquid crystal display device. Contents of the invention [0003] In view of this, it is necessary to pr...
