Display panel, driving circuit and display device

Abstract

The invention discloses a display panel, a driving circuit and a display device. The display panel includes: a first substrate, a second substrate and a third substrate respectively arranged on both sides of the first substrate; A first display mode liquid crystal is arranged between the first substrates; a second display mode liquid crystal is arranged between the third substrate and the first substrate; wherein, the first substrate is an array substrate or a color filter substrate The second substrate and the third substrate are color filter substrates or array substrates corresponding to the first substrate; the array substrate or the color filter substrate is a light emitting substrate. The advantages of the display panel, driving circuit and display device being compatible with different liquid crystal display modes can further meet the diverse needs of users, improve the functions of the display panel and improve user experience.

Description

technical field [0001] The present invention relates to the technical field related to liquid crystal display, in particular to a display panel, a driving circuit and a display device. Background technique [0002] Existing liquid crystal display panels are usually formed by pairing a color filter substrate and an array substrate, and then a liquid crystal is arranged between the color filter substrate and the array substrate. However, based on the difference in liquid crystal between the color filter substrate and the array substrate, LCDs usually have TN, ADS and VA three different display modes. figure 1 The cross-sectional device and schematic diagram of the display principle of the existing TN type (twisted nematic) display panel are given. The TN type display panel mainly includes three parts: 1 is the CF color filter substrate, 2 is the liquid crystal, and 3 is the TFT array substrate. When the device is in the OFF state, the optical path passes through the aligned l...

Problems solved by technology

[0003] In addition, the above-mentioned TN-type display panel and ADS-type display panel have their own advantages and disadvantages. The most obvious is that the TN-type display panel has high brightness, but the viewing angle is relatively small, while the ADS-type display panel has relatively low brightness, but the viewing angle is relatively large.

However, with the popularization of diversified applications of mobile phones and tablet computers, existing mobile phones or tablet computers cannot meet the needs of customers. For example, when using mobile phones or tablet computers to play videos and movies, users often hope to People share together, so it is hoped that the panel can achieve a relatively wide viewing angle. When users use mobile phones or tablets to handle private business (such as sending text messages, sending and receiving emails, etc.), they need some privacy, and hope that the panel can have a relatively narrow viewing angle. At present, the single TN panel or ADS panel of the mobile phone panel cannot meet these two requirements at the same time.

[0004] Therefore, in the process of implementing the present application, the inventor found that the prior art has at least the following defects: the single display mode in the current display panel cannot meet the diverse needs of users
