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.

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which
