In the process of using the DLP large screen display system, the user's most problematic is that the brightness of the image display will gradually darken over time. Sometimes there will be between the unit and the unit can be resolved with the naked eye color. Here we have sorted out some common problems, as well as solutions, we hope to help.
DLP large screen splicing system is composed of a number of rear projection unit combination, the unit and the unit between the color is inconsistent, if the eye can be easily resolved, we put this difference called color.
DLP large-screen projection system circuit system and the light system consists of a large number of electronic devices and optical devices, each electronic devices and optical devices, electrical parameters and optical parameters are not exactly the same, even with the same process, the same batch Products, their parameters are subtle differences, these subtle differences have been enough to cause significant color. Among them, the projector inside the color wheel and light bulbs, DLP projector external multi-screen graphics card is the main factor in color. To this end, each rear projection unit design of the color balance circuit, the circuit can adjust the image output R, G, B color components, so that the color difference between the units to minimize. Therefore, through the manufacturer's strict quality management and on-site installation staff carefully adjusted, the color difference can be basically eliminated. However, things are not so simple, so the process of the large-screen system, with the passage of time and the external environment (such as temperature, humidity, external voltage, etc.) changes in electronic and optical device parameters also change, In addition, due to operator errors or electrical shocks, stored RGB parameters may also be lost, these factors will cause the color of the re-generation. Therefore, the regular adjustment to ensure that the system's smallest color. Color adjustment requires a certain degree of technical training and experience accumulation, the end user is generally difficult to do, often need to send the system to send technical staff to solve.
The color difference is a common concern for the DLP large screen display system industry. To solve this problem, on the one hand need to rely on the continuous progress of technology (such as the use of fully digital circuit) and the manufacturer's strict quality management, more serious is the system supplier perfect after-sales service system.
