Description

Technical Field

[0001] The utility model relates to the technical field of TFT display screens, in particular to a TFT screen that can be quickly assembled. Background Art

[0002] TFT LCD is an advanced technology that has been widely used in modern electronic products. Today we will introduce the principles, characteristics and application scenarios of TFT LCD. TFT LCD is a passive liquid crystal display whose liquid crystal molecules are arranged in a directional manner to control the passage of light. The basic principle is that a layer of liquid crystal molecules is sandwiched between two parallel electrodes. When voltage is applied to the electrodes, the liquid crystal molecules will change their arrangement, thereby blocking or passing light to form an image. As an advanced technology, TFT LCD has the advantages of high definition, high contrast, fast response, low power consumption and suitability for large-screen production. It is widely used in various fields. In the future, with the continuous advancement of technology, TFT LCD will have more functions and wider applications.

[0003] For example, a TFT screen fixing structure with application number CN201920171607.4. It includes a touch screen, a display screen, a screen pressing bracket and an adapter plate arranged in parallel layer by layer, and four pre-fixed buckles are formed on the screen pressing bracket accordingly, so that the adapter plate and the screen pressing bracket can move along an L-shaped moving path and form a pre-positioning. The TFT screen fixing structure of the utility model utilizes the pre-fixed structural scheme between the screen pressing bracket and the adapter plate, which can make installation more convenient, reduce the number of locking screws, meet the requirements of the automated screw locking process, and will not be affected by the bending stress of the display screen soft cable of the display screen and the touch screen soft cable of the touch screen and other external stresses. The fixing of the entire TFT screen is more stable and reliable. However, the TFT display screen does not have a quick-release function, and the operation is relatively complicated during assembly or disassembly. In view of this, the shortcomings of the existing structure are studied and improved, and a TFT screen that can be quickly assembled is proposed. Utility Model Content
