Embodiment Construction

[0066] image 3 is a schematic cross-sectional view showing a display device 50 of the present invention. The display device 50 includes a light source 52 , a light guide plate 54 , a display panel 56 and a frame 58 .

[0067]The light source 52 includes a lamp tube (not shown) and a reflector (not shown), wherein the reflector surrounds the lamp tube. In this embodiment, the light source 52 is realized by using a light emitting diode (LED). In other preferred embodiments, the light source 52 may also be a cold cathode fluorescent tube (CRT), or be replaced by ambient light (for example: outdoor light) or sunlight. The display device 50 includes an integrated circuit (IC) 70 for the display panel 56 , and the IC 70 is used for driving the display panel 56 . In this embodiment, the integrated circuit 70 is a flexible printed circuit (FPC).

[0068] The light guide plate 54 is used to guide the light 52 - 2 of the light source 52 to the display panel 56 . In a preferred emb...

Abstract

A display device that comprises a first viewing face allowing viewing of a first image on display from a first direction, a second viewing face allowing viewing of a second image on display from a second direction, a light source, a transparent substrate, a light guide plate receiving light provided by the light source, a surface of the light guide plate that transmits the light toward the first viewing face, and a plurality of reflective regions provided -over the transparent substrate that reflect the light transmitted from the surface toward the second viewing face.

Description

technical field [0001] The invention relates to a display device, in particular to a display device with double screens. Background technique [0002] A general display device provides the required light source through a backlight assembly or a front light assembly. The backlight or front light assembly usually includes a light tube and a light guide plate to provide uniform brightness to a display panel of the display device. There are quite a variety of electronic products using flat panel displays, such as notebook computers, televisions, digital watches, calculators, telephones, and mobile phones. The mobile phone will be used as an example to provide relevant descriptions below. [0003] Figure 1A and 1B A known electronic product 10 (such as a mobile phone) is shown, and the electronic product 10 has a shell-like appearance. Such as Figure 1A As shown, the electronic product 10 includes an operating component 12 and a display panel 14, wherein the display panel 1...
