Looking at the development trend of the projection market through the development history of resolution

Foreword: XGA used to be one of the display resolutions we have been using for the longest time, namely 1024x768. I remember that the resolution of the 17-inch CRT monitor on my first desktop computer was XGA. I used it from 2003 to 2010 and spent countless nights with me. Later, CRT monitors were gradually replaced by 17, 19-inch LCD monitors, and the screen ratio gradually changed from 4:3 to widescreen (16:9 or 16:10)...Technical lectures XGA (Extended Graphics Array) is one A computer display mode. The display mode refers to the performance of the monitor, especially the maximum number of colors and the maximum image resolution. XGA, also known as Extended Graphics Array, is a standard introduced by IBM in 1990. XGA supports 1024×768 resolution, 256-color palette (8 bits per pixel). XGA-2 further supports 1024×768 (high color, higher frame rate). XGA resolution has been launched by IBM in 1990 and has a history of 23 years. We have to admire its vitality for such a display resolution that can last for such a long time. It also starts with XGA, and the screen display ratio also begins. From the general screen (4:3) to the widescreen conversion. Up to now, with the emergence of resolutions such as WXGA, HD1080, 2K, WUXGA, 4K, and 8K, XGA can still have super vitality. Especially in the field of projector display, the sales of XGA resolution projectors account for the total number of projectors each year. Half of the sales are on the river, or even 3/4.　　High resolution and high image quality are the development direction of the display field, and now, in the face of the ever-increasing development momentum of resolution, how long can XGA stay strong? Moreover, in the field of popularization of full HD projection display, XGA is no longer a perfect partner for widescreen business notebooks, and XGA cannot meet the needs of more delicate teaching in teaching, and the entertainment aspect is full of full HD. Has XGA come to an end in this era, and how long can it be 'red' in the field of projection display? At present, XGA models account for a high proportion of the total annual projection sales, but the main reason is that XGA display chips have a great advantage over higher resolution chips, and the development of the projection industry is not like other displays. The industry is developing so rapidly and popularly. When the prices of higher-resolution chips gradually drop and chip manufacturers increase their production and shipments of high-resolution chips, XGA will usher in its end. With the advent of the era of high-definition and even 3D signals, people have higher and higher requirements for product resolution, which also means that more and more delicate pixels will become a direction for the development of projectors.　　 On the other hand, the development of computer display devices is constantly stimulating the high resolution of projectors. As a kind of display equipment, projection products should also conform to this trend. Since most of the users who use the projector also use the laptop at the same time, it is necessary to choose the same resolution as the computer in order to make the projector show the most perfect effect.
