Embodiment Construction

[0032] Since the liquid crystal itself does not emit light, the traditional TFT-LCD needs a backlight source to provide the light required for display. However, the setting of the backlight will inevitably lead to higher power consumption, larger thickness, and higher weight of the product, which limits the wider application of TFT-LCD. For example, traditional TFT-LCD does not meet the requirements of portable applications.

[0033] In order to solve the above technical problems, the present invention provides a reflective liquid crystal display panel and a display device, which provide the light required for display by reflecting ambient light, eliminating the need for a backlight source, greatly reducing the power consumption of the product, and having a small thickness , Low weight and other advantages.

[0034] The reflective liquid crystal display panel in the present invention includes a first substrate and a second substrate arranged opposite to each other, and liquid ...

Abstract

The invention relates to the field of display technology, and discloses a reflective liquid crystal display panel, a display device and a driving method thereof. Both the first substrate and the second substrate of the reflective liquid crystal display panel include an optical waveguide structure, and the principle of total reflection can be used to make the ambient light incident into the pixel area undergo total reflection, and will not be emitted to the display side, so as to realize dark state display . When the ambient light entering the pixel area does not meet the conditions of total reflection, it can be emitted to the display side to achieve bright display without polarizers, so there is no loss in the refractive index, and the light utilization rate is increased by more than 50% without reducing Color gamut, the picture display effect is good. At the same time, the light is exported from the side, and the contrast is high, which greatly improves the pixel quality. The structure and process of the scheme are simple and easy to realize. Since the backlight source is omitted, the power consumption of the product is greatly reduced, and it also has the advantages of small thickness and low weight.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflective liquid crystal display panel, a display device and a driving method thereof. Background technique [0002] At present, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has been widely used. Many laptop and desktop monitors are TFT-LCD. TFT-LCD already has a very high resolution and Color active image display capability, but also sufficient display brightness. But because the traditional TFT-LCD needs a backlight source, the fly in the ointment is that the power consumption is considerable and it occupies a certain space. The thickness and weight of TFT-LCD restrict its wider application. Contents of the invention [0003] The invention provides a reflective liquid crystal display panel, a display device and a driving method thereof, which are used to solve the problems of high power consumption, large thickness and high weight of the product due to the trad...
