Liquid crystal display screen for emitting light through quantum dots

Abstract

A liquid crystal display screen for emitting light through quantum dots comprises a planar polaroid, a liquid crystal box, a bottom polaroid and a quantum dot light-emitting board. The planar polaroidis arranged on the upper side of the liquid crystal box. The quantum dot light-emitting board is arranged below the liquid crystal box. The bottom polaroid is arranged between the quantum dot light-emitting board and the liquid crystal box. The quantum dot light-emitting board comprises a sealed frame, a brightening membrane and a quantum dot material layer. The quantum dot material layer is arranged in the sealed frame. The brightening membrane is arranged on the upper side of the sealed frame. The quantum dot material layer comprises an AI electrode, an electronic transmission layer, a quantum dot light-emitting layer, a hole transport layer, ITO electrodes and a PET substrate. The ITO electrodes are arranged on the left side and the right side of an isolation plate respectively. The AIelectrode, the electronic transmission layer, the quantum dot light-emitting layer and the hole transport layer are sequentially overlapped on the ITO electrode on the left side of the isolation plate from top to bottom. One end of the AI electrode extends to be connected with the ITO electrode on the right side of the isolation plate. Electroluminescence is conducted through the quantum dot material layer, and the short-circuit phenomenon is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a liquid crystal display screen using quantum dots to emit light. Background technique [0002] After continuous development of liquid crystal display, from the TN\STN liquid crystal display that can only display simple black and white character graphics at the beginning to the current mainstream TFT liquid crystal display, it can display various pictures with rich content and bright color effects. With the promotion and popularization of liquid crystal display applications, TFT liquid crystal displays are favored by consumers because of their fast response time and high-quality display effects. However, due to their complicated manufacturing process and high cost, they are currently only used Used in high-end consumer electronics products. [0003] The current digital products have increasing requirements for liquid crystal display modules. However, consumers also ...

AI Technical Summary

Problems solved by technology

However, this structure has the following problems: when the device frame is biased, two metal clips are used to clamp the AI ​​electrode and the ITO electrode. In this case, due to the thickness of the entire device film (excluding the glass substrate) But about a few hundred nanometers, the metal clip clamped on the AI ​​electrode can easily penetrate the AI ​​electrode film, even penetrate the active layer, and be directly connected to the ITO electrode, and the other metal clip is also connected to the ITO electrode. It causes a short circuit of the whole device and affects the service life of the display screen.
