Computer screen resolution has always been a concern of the majority of computer users, because the resolution determines the picture quality of the screen display, but many friends do not understand what the computer screen resolution means. It is normal to not understand, let us figure this out by studying this article! Resolution is called resolution in English. We call it resolution in mainland China, and it is often called resolution in Taiwan and Hong Kong. Resolution refers to the precision of the computer screen graphics, that is, how many pixels the display can display. We know that the display screen is actually a whole of dots, lines and faces made up of numerous LCD dots. The more pixels the display can display, the finer the picture, and the more information that can be displayed in the same screen area. We can understand that the more points in a region are evenly distributed, the whole area will be fuller and look more like a complete plane. The more points, the finer and clear the whole surface. Generally speaking, the resolution refers to the product of the number of horizontal pixels and the number of vertical pixels. For example, our most common 1024X768 resolution means that the number of horizontal pixels is 1024, the number of vertical pixels is 768, and the entire area has 1024×768=786432 (pixels). The higher the resolution, the more pixels in the display screen area, the more precise the image, the more delicate and clear the display. In addition, the resolution of the display quality is also related to the size of the display. The larger the screen, the higher the resolution should be, in order to achieve a more delicate image quality. I believe that it is easy for everyone to understand that as the size of the display becomes larger, the number of pixels required must be increased to achieve higher image quality. The final resolution is also affected by factors such as the pixel pitch and video bandwidth. Among them, it has a close relationship with the refresh frequency. Strictly speaking, only when the refresh frequency is “no flicker refresh frequency”, the display can reach the highest resolution, which can be called the highest resolution of this display. Editor's Note: High resolution is an important prerequisite for ensuring the clarity of color displays. The dot pitch of the display is one of the foundations of high resolution, and the dot pitch of the large-screen color display is generally 0.28, 0.26, 0.25. The other aspect of high resolution refers to the maximum pixel point that the display can achieve in horizontal and vertical display. Generally, there are 320×240, 640×480, 1024×768, 1280×1024, etc., good large screen color display. It is usually able to achieve a high resolution of 1600 x 1280. Higher resolution not only means higher definition, but also means more content can be displayed in the same display area. For example, only one page of content can be displayed at 640×480 resolution, and two pages can be displayed simultaneously at 1600×1280 resolution. Finally, with the popularity of high-definition technology, the screen resolutions that we usually call 720P, 1080P HD movies usually reach 1920x1080 (width x height), 720P is 1280x720, because the naked eye is more sensitive to horizontal resolution, so Having a higher horizontal resolution, that is, the number of horizontal lines, that is, the number of lines we usually say, plays a decisive role in the definition of high definition images.
