What is the size of the LED panel?

parameter Because LED displays are based on LEDs, their light, electrical characteristics, and limiting parameters are mostly the same as those of light-emitting diodes. But because the LED display contains multiple light-emitting diodes, the following special parameters are required: 1. Luminous intensity ratio Because each segment of the digital tube has the same driving voltage, the forward current of each segment is different, so the luminous intensity of each segment is different. The ratio of the maximum value to the minimum value of the luminous intensity values ​​of all segments is the luminous intensity ratio. The ratio can be between 1.5 and 2.3, and the maximum cannot exceed 2.5. 2. Pulse forward current If the typical forward DC working current of each segment of the stroke display is IF, the forward current under pulses can be much larger than IF. The smaller the pulse duty cycle, the larger the pulse forward current can be. size The size of the CRT display refers to the diagonal size of the picture tube. The maximum viewing area is the maximum range of graphics that the monitor can display. The size of the picture tube is usually measured by the length of the diagonal, in inches (1 inch = 2.54cm), and common are 15 inches, 17 inches, 19 inches, 20 inches and so on. The display area will be smaller than the size of the display tube. The display area is expressed by the product of length and height. Usually people also use the diagonal length of the visible part of the screen. The viewing range of a 15-inch display is about 13.8 inches, the viewing area of ​​a 17-inch display is mostly between 15 and 16 inches, and the viewing area of ​​a 19-inch display is about 18 inches. Display size The size of the LCD display refers to the diagonal size of the LCD panel, in inches (1 inch = 2.54cm). The mainstream ones are 15 inches, 17 inches, 19 inches, 21.5 inches, 22.1 inches, 23 inches, 24 inches and so on. Added: mainstream notebook sizes are 10.1 inches, 12.2 inches, 13.3 inches, 14.1 inches, 15.4 inches, 17 inches.

Difference between led display and lcd display!

LED Display: LED Display, known as Light Emitting Diode Display, is a display device that uses Light Emitting Diodes (LEDs) as pixel points. It displays images or text by controlling the brightness and color of each LED. LED displays are characterized by high brightness, high contrast, wide viewing angle and long life.
