Why does the touch screen of the building advertising machine appear chromatic aberration? Such a situation is also known as light attenuation in the commercial display industry. After a monitor has been in operation for a period of time, it will undergo certain changes, regardless of whether any product will be more or less different from the original. Regardless of LCD or DLP splicing products, the machine will produce color attenuation after a period of use, and it is normal to have color difference. How do we slow down without being bothered by it. Today's simple explanation: Why does the touch screen of the building advertising machine appear chromatic aberration.

1. Control power: control the output power of the local oscillator in the microwave superheterodyne receiver, obtain the best noise figure and frequency conversion loss, achieve the best receiving effect, and realize automatic gain control to increase the dynamic range in the microwave receiver.

 2. Relative standard: as a relative standard for comparing power levels.

 3. Attenuator for radar anti-jamming: it is a variable attenuator that can attenuate attenuation. No attenuation is introduced, and when external disturbances are encountered, the attenuation increases suddenly.

       This has to do with the source of the device itself. The difference is that the decay of the liquid crystal is irreversible. With LCD devices, we don't have many ways to adjust the color, but its decay doesn't happen very often; DLP's color difference is largely due to the long-term use of the bulb. The easiest way is to adjust it by changing the bulb.
