Problems solved by technology

[0003] At present, liquid crystal display technology generally can only realize single-sided display, or single-sided touch display, that is to say, users can only watch the displayed content or perform operations on the front of the display device, which undoubtedly limits the scope of use of touch LCD devices.
For example: most of the existing mobile phones have a camera function. When the user takes a selfie, the lens is aimed at himself, and the display screen will face the user. On the one hand, the user cannot see his own image; Touch buttons to operate, very inconvenient to use
[0004] When implementing the technical solution of the present invention, the inventor found that the touch liquid crystal display device provided by the prior art has at least the following problems: it can only provide single-side touch and single-side display, which causes certain inconvenience to the user's operation and use

Embodiment 1

[0032] Because LCD (Liquid Crystal Display, liquid crystal display device) is a kind of transparent element, the application of prior art LCD usually uses backlight source panel to provide light source for this device, and backlight source panel is generally an opaque white backlight plate, that is, Only one-sided display can be performed, and most of the power consumption of this type of display device is concentrated on the backlight board. In order to realize the double-sided display and touch function of the liquid crystal display device, and further reduce its power consumption, the embodiment of the present invention provides A double-sided touch liquid crystal display device, such as figure 1 As shown, the device includes: a liquid crystal panel 1 with double-sided display screens, transparent touch panels 2 respectively arranged on both sides of the liquid crystal panel 1, and a touch panel arranged between the transparent touch panel 2 and the liquid crystal panel 1 T...

Embodiment 2

[0035] The double-sided touch LCD provided by this embodiment can realize images with the same or similarities and differences on the front and back sides. When the LCD displays the same image, the image is a symmetrical image with the Y axis as the symmetrical axis when viewed from the front of the screen and viewed from the reverse side of the screen. , that is to say, when viewed from the front, the displayed image on the right is actually displayed on the left of the reverse, and all display contents are like this. If the image content is not affected by symmetry, the LCD can display the same content, but if it is affected, for example, when displaying text, the front side can be read normally, but it cannot be read normally when viewed from the back side, then the double-sidedness of the display operation will be affected. Therefore, it is preferable to use the front and back sides of the same LCD to display different contents, which requires special processing on the LCD ...

Embodiment 3

[0042] On the basis of the previous embodiment, further, the pixels of the liquid crystal panel can be divided into three types, one type of pixels displays the front content, the other type of pixels displays the reverse content, and the third type of pixels is used for Translucent.

[0043] Such as Figure 4 and Figure 5 As shown, the pixels of the liquid crystal panel of the double-sided display screen include: the first pixel point A, the second pixel point B and the third pixel point C distributed at intervals, and the first pixel point A constitutes the first pixel point for displaying the front screen A display module 111 , the second pixel point B constitutes a second display module 112 for displaying a reverse image, and the third pixel point C constitutes a light-transmitting module 113 . Among them, the positions of the first pixel point A, the second pixel point B and the third pixel point C can be changed and combined arbitrarily to form various arrangements, s...

Abstract

The embodiment of the invention discloses a double-sided touch LCD device, and relates to the LCD field. The device realizes double-sided display and touch functions of the LCD device and lowers power consumption. The double-sided touch LCD device comprises a double-sided picture display LCD panel, transparent touch pads arranged at two sides of the LCD panel respectively and a transparent backlight unit arranged between the transparent touch pads and the LCD panel. The double-sided touch LCD device is applied to an LCD.

Description

technical field [0001] The invention relates to the field of displays, in particular to a double-sided touch liquid crystal display device. Background technique [0002] Due to its small size, low power consumption and no radiation, liquid crystal displays occupy a dominant position in the current display market, and can be widely used in communication, information or consumer electronics products such as notebook computers, digital cameras, camcorders, and mobile phones . [0003] At present, liquid crystal display technology generally can only realize single-sided display, or single-sided touch display, that is to say, users can only view the displayed content or perform operations on the front of the display device, which undoubtedly limits the scope of use of touch-screen liquid crystal display devices. For example: most of the existing mobile phones have a camera function. When the user takes a selfie, the lens is aimed at himself, and the display screen will face the ...
