What is Dynamic Contrast Error (DCE)?

It is a color difference test used to determine the quality of display devices. The DCE is performed by displaying the same color on two different backgrounds. It is the brightness difference between the two colors that is measured.

The DCE is designed to test the maximum brightness range of a display. This is an important factor in visibility, since it is the range between the highest brightness and lowest brightness of the background colors that determines the maximum brightness of the displayed colors. The DCE uses two color patches of identical color to test a display device.

The colors should be relatively pure. The color patches are displayed on two different backgrounds with a brightness difference of 100:1. The measurement is then repeated at a brightness level of 1000:1.

What causes Dynamic Contrast Error on NEC Projectors?

Dynamic Contrast

A Dynamic Contrast Error, or DCE, is an error that occurs in some NEC projectors. It occurs when the projector is not receiving a signal but it displays a blue screen or black screen.

The DCE error is caused by a problem in the horizontal output circuit, which is used for projecting the blue component of the color signal.

When the horizontal output circuit is broken, the blue component of the color signal is blocked and the red, green and blue components are output to the screen.

What are the symptoms of Dynamic Contrast Error?

Dynamic Contrast Error (DCE) is a common problem that most LCD monitor users face. This is a problem where the brightness of the screen changes unevenly. But what causes Dynamic Contrast Error?

DCE is caused when the LCD panel becomes dirty or the front glass becomes broken. The air resistance in the LCD panel of the monitor increases and the light from the backlight leaks out, causing the screen to lose its brightness.

Another problem that leads to DCE is when the backlight is broken. This happens when the wires in the LCD panel become loose and the backlight stops working.

The process of replacing the backlight is fairly simple and easy. One must just open the LCD panel, remove the backlight and replace it with a new one.
