A TFT display screen is an active matrix LCD driven by a thin film transistor (TFT). It is mainly composed of dots, lines, planes and backlights generated by current-stimulated liquid crystal molecules. Nowadays, people's requirements for TFT screens are getting higher and higher, and the attention is getting higher and higher, especially the 144Hz refresh rate e-sports display screen, which has become the main product of gamers. So what are the important TFT display parameters? Let's take a look!
At present, the resolution of the mainstream TFT display screen is 1920×1080 (1080P), of course, 2560×1440 (2K) and 3840×2160 (4K) can also be considered.
The size of the TFT LCD screen is actually the diagonal length of the display part, in inches (1 inch = 2.54cm). When the aspect ratio is the same, the actual area is proportional to the square of the diagonal length.
The response time of the TFT display screen is generally in milliseconds (ms), which refers to the response speed of the TFT display screen to the input signal. The shorter the response time, the better the clarity of the picture without the teleportation of the game screen being dragged away.
The improvement of the contrast ratio makes the picture more layered and the light and dark are clearly distinguished, which means that it is easier for the user to see the picture under the dark conditions of the scene. The contrast ratio of the TFT display screen is preferably between 60-80, and the brightness is preferably between 40-60. When playing games, it is recommended to adjust the brightness and contrast to between 80-100, so that the visual effect will be better.
HDR refers to the way of dynamically presenting contrast and color accuracy according to the situation of the scene, such as a movie gamer in a black scene, the general TFT display panel is almost all black, but some scenes in the dark can be seen on the TFT display with HDR, which is probably the so-called bright black. In order to realize HDR technology, the TFT display screen must have the relevant hardware design, which affects the price performance.
