But if this is done, no matter which method is used to display the image, the area that can be used to display the image is only a part, that is, the aperture ratio of the half-transparent method to display the image is relatively small.

Embodiment Construction

[0025] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals.

[0026] It should be understood that when describing the structure of a device, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean being directly on another layer or another region, or Other layers or regions are also included between it and another layer or another region. And if the device is turned over, that layer, one region, will be "below" or "beneath" another layer, another region. If it is to describe the situation directly on another layer or another area, the expression "A is directly above B" or "A is above and adjacent to B" will be used herein. In the present application, "A is located directly in B" means that A is located in B, and A is directly adjacent to B.

Abstract

The invention discloses a transflective display device. The device comprises a plurality of pixel units. Each pixel unit comprises a liquid crystal display device and an electrowetting display devicewhich are sequentially stacked. The transflective display device works in a transmission mode or a reflection mode; in the transmission mode, backlight is turned on, the light transmittance of the backlight is controlled by the liquid crystal display devices according to gray scale data to form an image, and the image passes through the electrowetting display devices; in the reflection mode, the backlight is turned off, the liquid crystal display devices are shut down, and the electrowetting display devices control the reflectivity of ambient light according to the gray scale data so as to form an image. According to the transflective display device, the opening rate can be increased due to a layer stacking mode.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a switchable transflective display device. Background technique [0002] There are three types of liquid crystal displays: transmissive, reflective, and transflective. Transmissive LCD has high contrast and high color purity, but consumes a lot of power and has poor visibility under strong ambient light; reflective LCD does not need a backlight, has low power consumption, light weight, and good visibility under strong ambient light. But the contrast is low, and it is difficult to achieve rich colors. In order to meet different needs, people often purchase two types of display devices at the same time, which is expensive and inconvenient to carry. The transflective liquid crystal display has the advantages of both transmissive and reflective displays, and has a large range of ambient light adaptation. The transflective liquid crystal display can display images in both tran...
