Description

Technical Field

[0001] The embodiments of the present application relate to the field of televisions, and in particular to a television back panel structure and a television structure. Background Art

[0002] With the continuous development of science and technology, people's living standards are constantly improving. In order to meet people's entertainment needs, LCD TVs came into being. LCD TV is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to form a picture with the back light tube. Under the action of the electric field, the arrangement direction of the liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction of the time domain and space domain through the three primary color filters of red, green, and blue. Among them, borderless LCD TVs have gradually become the mainstream, and borderless LCD TVs directly carry the screen through the back panel. In the existing assembly process, the optical film is limited by the film pressure strip.

[0003] However, in the existing solutions, the cost of limiting the position of the optical film by sticking the film strip is high, which is not conducive to low-cost production. Utility Model Content
