By the Affective of COIVD-19, as the leader of chip set touch sensor companies of ILITEK, is running out of the touch screen chipset, and all touch screens will increase in price.

In 2020, as the epidemic has stimulated people’s demand for work, study, entertainment and other applications at home, the display industry has achieved rapid development, and the upstream chip of the supply chain is also booming. Affected by the global chip shortage, display driver chips are facing price increases. According to data, the total demand for display driver chips is expected to grow to 8.4 billion in 2021. In the display driver chip market, Taiwanese design companies occupy a dominant position in the LCD field, accounting for nearly 80% of the market in 2020. Heria and ILITEK ranked first and second respectively. Due to the sudden attack of the epidemic in 2019, all factories were halted urgently, resulting in a shortage of ILITEK’s chip inventory. In addition, due to the global shortage of COVID-19 vaccines, only about 11% of Taiwan’s population has been vaccinated, which has caused difficulties for factories to resume work, and has exacerbated the problem of imbalance between supply and demand in the market. Chip prices will continue to rise in the future.

Advantages of ultra-narrow LCD splicing screen

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

What is liquid crystal?

Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.
