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

Example Embodiment

[0031] Example one

[0032] Since LCD (Liquid Crystal Display, liquid crystal display device) is a kind of transparent element, the application of the prior art LCD is usually to use a backlight panel to provide the light source for this device, and the backlight panel is generally an opaque white backlight panel. Only single-sided display can be performed, and most of the power consumption of this type of display device is concentrated on the backlight panel. 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 a double-sided display screen, a transparent touch panel 2 respectively arranged on both sides of the liquid crystal panel 1, and a transparent touch panel 2 arranged between the transparent touch panel 2 and...

Example Embodiment

[0034] Example two

[0035] The double-sided touch LCD provided in this embodiment can realize the same or similar images 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 symmetry axis when viewed on the front side of the screen and on the back side of the screen. That is to say, the image displayed on the right side when viewed from the front is actually displayed on the left side of the back side, 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 there is an impact, for example, when the text is displayed, the front side can be read normally, but when viewed from the back side, it cannot be read normally, then the display operation double-sidedness is affected. Therefore, it is preferable to use the front and back sides of the same LCD to display different content, which requires special processing on the LCD panel.

Example Embodiment

[0041] Example three

[0042] On the basis of the previous embodiment, the pixels of the liquid crystal panel can be further 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 Transparent.

[0043] Such as Figure 4 with Figure 5 As shown, the pixel points of the liquid crystal panel with a double-sided display screen include: first pixel points A, second pixel points B, and third pixel points C distributed at intervals. The first pixel points A constitute the first pixel point that displays the front image. 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 arbitrarily changed and combined to form a variety of ar...

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 ...
