Quais são os cuidados para a compra do display LCD:
1. Dot spacing should be as small as possible
Dot pitch is the distance between the center points of adjacent pixels on the LCD display. The smaller the dot pitch, the more pixels per unit area, the higher the resolution, the closer the shooting distance can be, and of course the more expensive it is.

2, the filling factor should be high
The fill factor of an LCD display is also called the ratio of bright area, which is the ratio of the light-emitting area of each pixel to the physical surface area occupied by the pixel. When viewed at close range, the picture is inconsistent and incomplete, and uneven brightness produces graininess. If the light-emitting source is limited to a small pixel surface area, so that the brightness of a single pixel is several times or even ten times the brightness of the entire screen, it will Causes a more serious glare.
3, the color temperature can be adjusted
When the studio uses the LCD screen as the background, its color temperature should be consistent with the color temperature of the lights in the studio, so that accurate color reproduction can be obtained during shooting. According to the needs of the program, the studio lighting sometimes uses 3200K low color temperature lamps, sometimes 5600K high color temperature lamps, and the LED display needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results.
4. Ensure a good use environment
The failure rate of the product is low only under proper working conditions during its service life. As an integrated electronic product, the LCD display is mainly composed of a control board equipped with electronic components, a switching power supply, a light-emitting device, etc., and the life and stability of all these components are closely related to the operating temperature.
