Problems solved by technology

Generally, manufacturers choose to use CSTN, STN or OLED panel as the sub-panel 10 to reduce costs. However, compared with the main panel 10 of TFT-LCD, the sub-panel 12 of CSTN, STN or OLED has lower resolution and brightness
In addition, the design of the backlight assembly 16 disposed on the display 2 can only make most of the light directed toward the direction of the main panel 10, that is, the backlight assembly 16 cannot provide the same brightness in both directions.

[0059] Figure 2B It is a schematic cross-sectional view of the display device 20 of the electronic device 100 with double-sided display function according to the first embodiment of the present invention. Such as Figure 2A and 2B As shown, when the cover of the electronic device 100 is closed, the observable screen of the liquid crystal display is referred to as the first display surface 22 for short. The display device 20 includes a front light assembly 21 , a color filter 25 and a transmissive panel (TFT panel) 24 . The color filter 25 is disposed below the front light assembly 21 and above the transmissive panel 24 , and there is a gap 28 between the front light assembly 21 and the color filter 25 . The height of the gap 28 is about 0.1 mm to provide a safety height to prevent direct contact with the color filter 25 . The transmissive panel 24 includes a second display surface 23 . An integrated circuit chip (IC chip) 27 is disposed on the transmissive panel 24 .

[0069] Figure 3A It is a schematic cross-sectional view of an electronic device with double-sided display function according to the second embodiment of the present invention. The second embodiment is different from the first embodiment, especially, the arrangement of each component of the display device 20 is slightly different. Such as Figure 3A As shown, the display device 20 includes a first display surface 22', a color filter 25, a transmissive panel (TFT panel) 24, a front light assembly 21 and a second display surface 23'. The transmissive panel 24 is disposed below the color filter 25 and above the front light assembly 21 , and there is a gap 28 between the front light assembly 21 and the transmissive panel 24 . The height of the gap 28 is about 0.1 mm to provide a safety height to prevent direct contact with the color filter 25 . The first display surface 22 ′ is located above the color filter 25 , and the second display surface 23 ′ is below the color filter 25 ...

Abstract

A display device with double surface display function consists of front light component which a light guide plate and a light source being set at one end of light guide plate, colour filter on light guide plate, optical polarization film in between front light component and colour filter, transparent panel in between colour filter and transparent-reflecting polarization film.

Description

technical field [0001] The invention relates to a display device and an electronic device with double-sided display function, in particular to a display device which does not need to use a sub-panel so that both sides have the same color scale and resolution. Background technique [0002] Currently, there are many electronic products using flat panel displays, such as notebook computers, desktop computers, telephones, mobile phones, personal assistants, and televisions. The mobile phone will be used as an example to provide relevant descriptions below. [0003] Figure 1A and 1B The conventional mobile phone 1 is shown in open and closed states respectively, and the mobile phone 1 has a main panel 10 and a sub-panel 12 . Figure 1C A schematic diagram of the backlight unit 16 of the mobile phone 1 is shown. The liquid crystal display 2 of the mobile phone 1 with double-sided display function is mainly composed of a main panel 10, a sub-panel 12 and a backlight assembly 16...
