The contrast determines the clarity of the transparent LED display, which has a great influence on the display effect. The size of the viewing angle marks the increase of the brightness change rate on the transparent LED display with the deviation from the normal direction, and the transparent LED is calibrated. Uniformity of brightness at each viewing angle of the display. And in the case of other indicators, the viewing angle and contrast basically determine the display effect of the transparent LED display.
The definition and influence factors of the viewing angle of the transparent LED display
We know that TV sets, computer monitors and LCD screens all have a viewing angle. This is also true in the field of transparent LED displays. What is the viewing angle of the transparent LED display? What is the viewing angle and what factors? The following small series will introduce to you.
Transparent LED display definition angle
The viewing angle is the angle at which the user can clearly observe all the content on the screen from different directions. The viewing angle can also be understood as the ability to see the maximum or minimum angle of the screen. And the viewing angle is a reference value, and the transparent LED display viewing angle includes two indicators of horizontal and vertical.
The definition and influence factors of the viewing angle of the transparent LED display
Wide viewing angle | 160° viewing angle
Side Emitting lamp bead construction, viewing angle 160°, wider spread surface, better communication effect, covering 90% of advertising audience
The technical parameters are described in this way (visual angle: 160°/160°); the maximum viewing angle is 140°, and the maximum viewing angles of horizontal and vertical are 160°. After more than 160 degrees, the viewing effect is poor or exists. Blind zone.
The horizontal viewing angle indicates that the vertical normal line of the transparent LED display (ie, the vertical imaginary line in the middle of the LED display) is correct, and the display can still be normally displayed at a position perpendicular to the left or right of the normal line. Image, this angle range is the horizontal viewing angle of the transparent LED display; also if the horizontal normal is taken, the upper and lower viewing angle is called the vertical viewing angle. In general, the viewing angle is based on contrast changes. When the viewing angle is increased, the contrast of the displayed image seen at the position will decrease, and when the angle is increased to a certain extent, the contrast is reduced to 10:1, which is the maximum viewing angle of the transparent LED display.
Factors affecting the viewing angle of transparent LED displays
The larger the transparent LED display is visible to the viewer, the better the viewing angle. However, the size of the viewing angle is mainly determined by the way the die is packaged, so it must be carefully considered when packaging the die.
The viewing angle of the transparent LED display has a great relationship with the viewing angle and distance. However, most LED display manufacturers are unified at present. If you customize the angle according to the situation on the spot, the cost will be high. It should be noted that the same chip, the greater the viewing angle, the lower the brightness of the transparent LED display.
