Embodiment Construction

[0015] Please refer to FIG. 2 , which is a schematic structural diagram of a first embodiment of a dual-screen liquid crystal display device of the present invention.

[0016] The dual-screen liquid crystal display device 200 includes a first liquid crystal panel 212, a first optical film group 211, a second liquid crystal panel 222, a second optical film group 221, a light guide plate 230, a light source 240 and a frame 250. The light guide plate 230 includes a light incident surface 233, a first light exit surface 231 and a second light exit surface 232. The first light exit surface 231 is opposite to the second light exit surface 232. It is connected with the second light emitting surface 232 .

[0017] The first optical film set 211 and the second optical film set 221 may be a combination of a diffusion sheet and a brightness enhancement sheet.

[0018] The first liquid crystal panel 212 , the first optical film set 211 , the light guide plate 230 , the second optical fi...

Abstract

A liquid crystal display unit with two screens is prepared as stacking the first liquid crystal face plate, the first optical diaphragm set, a light guide plate, the second optical diaphragm set and the second liquid crystal face plate in sequence; setting the second liquid crystal face plate to be smaller than the first one and setting the second optical diaphragm to be smaller than the first one.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a double-screen liquid crystal display device. 【Background technique】 [0002] Liquid crystal display devices have been widely used in mobile communication products such as handheld computers and mobile phones due to their advantages such as low radiation, light and thin size, and low-voltage driving. However, with the progress of the times, many products use the function of dual-screen display, such as a foldable dual-screen display mobile phone, the secondary display on the shell can display the date, time, number or name when calling, or A reminder to receive a text message; the main display screen in the shell can display main function screens, such as text message content, game interface and so on. [0003] Two liquid crystal display modules are required to achieve the dual-screen display function of the liquid crystal display device, and two single-sided display sub-mod...
