The cross-sectional shapes of the four frames can be the same, or different cross-sectional shapes can be designed according to the requirements of ultra-narrow frames, which can reduce the width of the frames around the non-display area and make the frame of the entire structure extremely narrow.

[0022] The frame cross-section design has a pressed light guide plate structure with the function of the middle frame in the conventional display structure, which can remove the middle frame structural parts. The frame cross-section structure is designed with a bonded full-fit liquid crystal glass structure with the function of the front shell in the screen assembly, which can remove the front shell structural parts, reduce the use of resources, and achieve cost reduction.

[0023] The frame uses the same set of extrusion dies to produce profiles of specified lengths, and the profiles are then machined to obtain four frames of different lengths. According to the different sizes of display screens, different lengths can be obtained through machining, so as to achieve a universal extrusion frame display structure that allows a set of extrusion dies to be compatible with a variety of display screens. A certain amount of frame profiles can be stored in stock before machining, which is convenient for inventory management, shortens the production cycle, and thus reduces costs.
