Description

Technical Field

[0001] The present utility model relates to the technical field of displays, and in particular to a liquid crystal display with adjustable viewing angle. Background Art

[0002] A liquid crystal display (LCD) is an active-matrix liquid crystal display (LCD) driven by thin-film transistors. It primarily uses electric current to stimulate liquid crystal molecules to generate dots, lines, and surfaces, which, in conjunction with backlighting, form the display. IPS, TFT, and SLCD are all subcategories of LCD. Its operating principle is that, under the influence of an electric field, the alignment of liquid crystal molecules changes, altering (modulating) the transmittance of an external light source, achieving electro-optical conversion. Then, using different excitations from the three primary color signals (R, G, and B), color reproduction in both the temporal and spatial domains is achieved through the red, green, and blue primary color filters. For example, patent (CN218409264U) discloses a monitor stand. Because the mounting base and the ball head of the rotating shaft form a universal rotating structure, the mounting base and, consequently, the display's mounting angle can be adjusted, thus meeting the varying viewing angles of different operators. However, during installation, the monitor requires external power and signal cables, which can easily become tangled during rotation, limiting the monitor's rotation angle. Utility Model Content
