Embodiment Construction

[0043]The inventor has conducted sufficient research and experiments on the structure of the liquid crystal display device, and proposed the technical proposal of the liquid crystal display device of the present invention on the basis of extensive practice. Wherein, the liquid crystal display device includes at least one solar cell, the solar cell can be arranged in the transmission path of the backlight light, and the non-transparent member faces the side of the backlight light, so that the The backlight light that contributes to the display is collected and utilized, and converted into electrical energy to power the liquid crystal display device; in addition, the size of the solar cell can also be set to be consistent with the non-transparent member, thereby The configuration of the solar cell will not affect the normal display and aperture ratio of the liquid crystal display device. On this basis, the inventor further proposes that the liquid crystal display device may also...

Abstract

The invention relates to a liquid crystal display (LCD) device. The LCD device at least comprises a liquid crystal box and at least one solar cell, wherein the liquid crystal box at least comprises a first base plate taken as a color film base plate, a second base plate taken as an array base plate, and a liquid crystal layer positioned between the first base plate and the second base plate; the first base plate and the second base plate at least comprise a transparent substrate respectively; and the at least one solar cell is arranged in a transmission path of internal backlight of the LCD device and/or the transmission path of externally ambient light which is transmitted into the LCD device for receiving the backlight and/or the externally ambient light. By the LCD device, various non-transparent parts in the LCD device and the internal backlight and the externally ambient light are fully used for acquiring electrical energy, so that the electric consumption is reduced, and the display time is prolonged.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device using solar cells to provide electric energy. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has the advantages of thinness, lightness, low power consumption, digitization, etc., and is currently being more and more widely used in the market. Since the liquid crystal itself does not emit light and cannot rely on natural light for lighting, a backlight must be used to obtain a stable and clear display. Generally speaking, the electric energy of the backlight source comes from an external battery, such as a lithium battery, and the storage capacity of the battery is limited, and it needs to be charged after each use, which brings inconvenience to the user. [0003] A solar cell is a device that uses the photovoltaic effect to convert solar energy into electrical energy. refer to figure 1 , in a conventional s...
