Digital cameras are more and more recognized by people. In terms of maintenance of digital video cameras, I believe that there are still many puzzles. The maintenance of digital camera LCD screens should be the most important part. Then the color LCD screen is an important feature of the digital video camera. Not only is it expensive, but it is also vulnerable to damage. Therefore, special attention should be paid to protecting the digital camera LCD screen during use. This will make the digital camera LCD screen youthful. First, the maintenance of the digital camera LCD screen 1. Avoid using digital cameras for a long time Everyone knows that all electrical appliances generate heat, and if used for a long time, components will be over-aged or even damaged. The pixels of a digital video camera are constructed by a large number of liquid crystals. Long-term continuous use will generate a large, high amount of heat. If this large amount of heat is not released in time, it may cause a high internal display. The temperature, while at too high temperature, the performance and service life of the liquid crystal display will be greatly reduced, some solder joints may be opened due to solder melting off, making the display unstable, and at the same time The device also accelerates aging, eventually causing the display to "strike" and, in the worst case, breaking or burning other components. In order to avoid burnout inside the screen, you should do the following when you are not using a digital video camera: (1) Turn off the digital camera LCD screen when nothing happens. (2) often changing the display content on the screen at different time intervals; (3) reduce the brightness of the display to a relatively dark level; (4) Display - a kind of all-white screen content. 2, maintain the appropriate humidity and temperature of the digital camera Water has always been the "natural enemy" of liquid crystal. When using a digital video camera, be careful not to let the LCD screen get water or be placed in a place with high humidity, so that the number in the display will become very blurred, and the more serious moisture will damage the inside of the LCD screen. The components cause corrosion of the liquid crystal electrode, causing permanent damage. Therefore, when shooting on a cloudy day, try not to use the LCD screen to view the scene, and use the viewfinder to view the scene. If the water vapor enters the display, don't be alarmed. Just put it in a warm place. For example, under the desk lamp, gradually evaporate the water inside. Alternatively, you can contact the dealer to have them take the machine and dry it in a dedicated heat engine room. In addition, it is important to maintain a certain operating temperature of the digital camera. It is recommended that the operating temperature be 0 ° C to 40 ° C and the storage temperature be -20 ° C to 60 ° C. It is necessary to understand that the state of the liquid crystal is not constant, and it will exhibit a transparent liquid state after being heated, and a particulate turbid solid will crystallize upon cooling. Therefore, the LCD princess is a bit squeamish, the surrounding temperature is too high or too low, the display surface will appear black, it will not work. 3, to avoid vibration and heavy pressure digital camera LCD screen The display of the liquid crystal is very delicate, and it may damage the quality of the display and the internal liquid crystal molecules of the display during the process of violent movement or vibration, so that the display effect is greatly reduced. In addition to avoid strong shocks and vibrations, it contains a lot of glass and sensitive electrical components in the middle, falling to the floor or other similar strong impact can cause damage to the screen or other units. Since there is an alignment layer in the liquid crystal display, it can make the liquid crystal molecules oriented in a certain direction, but it is extremely fine and cannot withstand excessive pressure. Therefore, do not point your finger at the display. Do not put a lot of pressure on the surface of the LCD screen. If you accidentally press the middle of the LCD screen with your hand, you need to wait at least one hour before powering up. 4, to prevent dust from entering the digital camera inside the LCD screen If dust accumulates on the internal circuits and components of the display for a long time, it will affect the heat dissipation of the electronic components, causing the temperature of the components such as the circuit board to rise, causing leakage and burning the components. In addition, dust may also absorb moisture and corrode the electronic circuitry inside the display, causing some inexplicable problems. Therefore, the dust volume is small, but the damage to the display cannot be underestimated. Firstly, the display should be placed in a clean and clean environment, but the dust is non-pervasive, so in addition to keeping the environment clean, after use, it should be put into the bag in time to prevent dust from entering. In addition, in the use and storage, it is more important to pay attention not to drop the camera to the ground to avoid breaking the LCD screen. The brightness of some color LCD displays will decrease with the temperature drop. This is normal and does not need to be repaired. When the temperature is quite low, the brightness of the LCD display will be very low. Once the temperature rises, the brightness will automatically return to normal; behind the color LCD screen, there is a light that cannot be seen from the surface, if the color LCD display The image becomes darker, or the spot on the image is displayed, or the image cannot be displayed at all, and most of the time is caused by the aging of the light bulb. In this case, generally, the corresponding light bulb can be replaced. Second, the digital camera LCD screen cleaning A large number of function settings on the digital video camera are required to be completed through the menu system on the display. Therefore, it is very necessary to maintain the clean and clean LCD display, then how to clean the LCD screen. 1, cleaning the digital camera display First choose the right cleaning agent, there are a variety of screen cleaners on the market, some are quite expensive, but we don't have to buy it so expensive, as long as it is a kind of flexible detergent that does not contain ammonia at home. Can be used because ammonia-containing cleaners can damage the surface coating of the display. When preparing for cleaning, remember to turn off the power of the display, then carefully wipe it from the center of the screen with a soft dry cloth or detergent. Wipe it lightly, otherwise the display screen will be short-circuited. In addition, do not wipe with a chemical solution such as alcohol, or use a rough cloth, paper or the like to wipe the display, and do not spray liquid directly onto the screen to prevent moisture from entering the inside of the display. In addition to the display screen, you should also use a brush and a small vacuum cleaner to often wipe the dust and dirt on the display case, as shown in Figure 3, but try not to wipe it with a damp cloth dampened with water. There is also a simple method, which uses a transparent adhesive to stick to the screen, and then peels off, so that the place where the transparent glue is pasted on the LCD screen is clean. 2, remove scratches on the display of the digital camera It's very convenient to clean, but the digital camera takes a long time, and it is inevitable that there will be scratches or streaks of one kind or another. What should we do? In most of these cases, the display is not affected, but the plastic cover used as a protective panel withstands these pressures and frictions. Because the frequent use of the camera can cause the screen to become old, speckled, or noticeably scratched, these phenomena will inevitably make the data on the display more and more illegible, especially when the sun is shining on it. In fact, this process is also very simple, you can go to the store to buy a small screen polish, which can be used to eliminate the nasty scratches on the LCD screen of the digital camera and the stains that appear after use. It is also very simple to use: first squeeze a little on the display, then rub a scratched area with a piece of cotton for 2 to 3 minutes, and finally wipe off the excess polish. It can be repeated several times as needed until the scratches are removed. Third, the removal of common problems with digital cameras Digital video cameras take a long time, and LCD screens often have various problems. Here are some common problems and solutions are provided for reference. 1, the digital camera display is dimmed In the LCD screen, the only part that is gradually consumed is the light bulb behind the display that cannot be seen from the surface. After long-term use, if you find that the LCD screen becomes dim, or if you display a spot on the image, or you can't display the image at all, it is mostly caused by the aging of the light bulb. In this case, you can usually replace it with the backlight. Come back to life and become the same as the new one. 2, the digital camera LCD display is not normal Under normal circumstances, the LCD monitor should be able to display the current status normally after power-on, and the display can respond accordingly as the function settings change and the shooting progresses. If the LCD monitor does not display the current status normally after power-on, most of the cases are caused by poor battery contact or insufficient power. You can reinstall the battery or replace it with a new one. When replacing a new battery, be careful to replace it all. Do not mix old and new batteries. 3, large dark spots on the screen of the digital camera LCD screen This situation is largely due to external force compression. Under the pressure of external force, the polarizing plate in the liquid crystal panel will be deformed. This polarizing plate is like aluminum foil. It will not bounce itself when it is recessed. This causes the difference of the liquid crystal panel when it is reflected, so you will see it. In the dark part, this part is easy to find under the white screen. The general size is more than ten square millimeters, which is the size of the thumb. This will not affect the service life of the LCD screen. Please pay more attention in the future use. Press the LCD screen.
