digital signage with chromecast

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.

With the vigorous advancement of the country’s new infrastructure during the “14th Five-Year Plan” period and the development of the contactless economy in the post-epidemic era, enterprises, governments, transportation, education, medical and other fields will accelerate intelligent and digital transformation, and smart display terminals have become an industry An indispensable basic carrier in digitization. As the application scenarios of smart commercial display become more and more extensive, its industrial value is constantly improving, and it has become an important strategically significant field in the electronic information industry. As an important part of the LED display, it is natural to not miss this blue ocean market with unlimited prospects. Two commercial display products, digital signage and LED advertising machine, have occupied most of the outdoor commercial display market share in recent years. In today’s market, digital signage is dominated by outdoor commercial display, mainly LCD, and the current LED outdoor advertising machine is also a commercial display product that has only gradually emerged in recent years. Why did digital signage come into being? LCD or LED? Along with the development trend of digital information technology, commercial offices such as merchants, enterprises, and units have already begun to switch to digital propaganda. Traditional posters, leaflets, banners, etc. have all begun to show a substantial reduction, as there are many digital devices that can replace them, and the effect is even better. In today’s day when digital information becomes normal, digital signage has come into life, and the work of publicity and display

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.
