​The primary part of an LCD display is an LCD panel, or liquid crystal display. It is a flat panel with two glass panels layered on top of small liquid crystal cells. The crystals align and alter the amount of light that passes through them when an electric current is applied, creating an image that can be seen.

If customers encounter screen display problems and want to check whether they are caused by flexible cables, they can check from the following aspects, including appearance, material, process, and functional testing to distinguish: It should be noted that the display screen may not display normally sometimes not because of the flexible cable itself, but because of interface oxidation or motherboard problems, but the flexible cable is the easiest to check as a connecting component. Therefore, when distinguishing problems, multiple factors should be considered comprehensively, and you cannot just look at one point.

Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

With the advancement of technology, beauty devices have made great progress, especially the introduction of 3.97-inch IPS screens. 480*800 resolution, 1000 contrast, support for RGB and MIPI interfaces, high-definition and delicate full-viewing angle, high color saturation and many other advantages, and the compact size of these screens makes handheld devices easy to carry around, while IPS technology gives users a clearer viewing experience. In this article, we explore the various applications of this screen in beauty devices.

​An LCD temperature display is a kind of digital temperature display that shows the current temperature using a Liquid Crystal Display (LCD). It is frequently found in gadgets like air conditioners, weather stations, and thermometers.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.
