The development of technology projectors are widely used in work and study. A projector, also known as a projector, is a device that projects or reflects images or video onto a screen through digital light processing technology or LCD liquid crystal imaging technology. It can access corresponding images through different signal sources, computers, mobile phones, DVDs, and DVs. And video signals for playback. Do you know the common problems with the projector ? Xiaobian takes you to understand.
Talk about projector common problems :
Strictly prevent strong impact, crushing and vibration. Because the strong earthquake can cause the displacement of the liquid crystal film, affecting the convergence of the three LCDs during the projection, the phenomenon that the RGB colors do not coincide, and the lens and the mirror in the optical system may also be deformed or damaged, affecting the image projection effect, and the zoom The lens will damage the track under impact, causing the lens to become stuck and even the lens to be broken.
Pay attention to the dust and ventilation of the environment.
The polysilicon LCD panels we currently use are generally only 1.3 inches, some even only 0.9 inches, and the resolution has reached 1024X768 or 800X600, which means that each pixel is only 0.02mm, dust particles are enough to block it. Because the projector LCD panel is fully cooled, there is a special fan that supplies air to the air at a flow rate of several tens of liters per minute. After the high-speed airflow passes through the filter dust net, it may entrain tiny dust particles, which rub against each other to generate static electricity. Adsorbed in the heat sink system, which will have an impact on the projected image. Therefore, it is very important to prevent dust in the environment in which the projector is used. It is strictly forbidden to smoke because the soot particles are more easily absorbed in the optical system. Therefore, the filter screen at the air inlet should be cleaned regularly or regularly. At present, polycrystalline silicon LCD panels are more afraid of high temperature. Newer models are equipped with temperature sensors near the LCD panel. When the air inlet and the filter screen are blocked and the airflow is not smooth, the temperature inside the projector will rise rapidly. The temperature sensor will alarm and immediately cut off the light source circuit. Therefore, it is necessary to keep the air inlet open and clean the filter in time. The projector installed on the ceiling should ensure ventilation and heat dissipation in the upper space of the room. When we hoist the projector, we often only pay attention to the surrounding environment, and forget the problem of hot air rising. The projector working on the ceiling has a very different ambient temperature than the following, so we cannot ignore this.
Through the introduction of Xiaobian, I believe that everyone has some understanding of the common problems of projectors . When we encounter these problems in work and study, don't panic and bravely overcome the problems and hope to help everyone.
The copying table is also called the writing table and the light-transmitting table. It is currently the most used in animation and comics and is an essential tool.When using it, you can overlap multiple drawings together, and you can clearly see the patterns on the bottom drawing. Using this function, you can easily copy the bottom drawing on the top paper. Therefore, many beginners of painting I will use a copy table to copy my favorite works.
