With the wide application of LCD in vehicle products, instruments and other electronic products, there will always be flashing in the process of use, which will affect the use of customers. What we should do at this time? Now we would like to share with you the causes and solutions of LCD screen flashing： The frequency of the LCD screen itself is too high, resulting in the flash screen. However, in real life, it is rare for the device to flash due to high frequency. According to the industry technical personnel, people’s naked eyes have no sense of flicker for images over 60Hz, while the design standard of general LCD screens is basically within this data range, so under normal circumstances, the frequency will not be too high, but at the same time, the screen itself will not be excluded from failure. After testing by relevant instruments, it is really the fault of the screen itself. In addition to replacing the new monochrome LCD screen, it is to design the software related to the equipment. LCD flash screen solution: the best way is to increase the OSC frequency of IC to see the flash of LCD screen. Of course, if the LCD has separate row and column drivers, it can also be adjusted by setting the driver chip.   The frequency of LCD is close to that of light source. This is very common. Because the frequency of different light source is different, in some specific cases, when the frequency

LCD screen will be widely used in many electronic products, one thing has been widely welcomed, and you will want to solve some problems, and pay attention to some things, let’s talk about how to pay attention to the anti-static problem of LCD screen? Electrostatic adsorption of dust reduces the insulation resistance of components and shortens the service life; Electrostatic discharge (ESD) damage, resulting in electronic components cannot work; the electromagnetic field produced by electrostatic discharge has a large amplitude and a wide frequency spectrum. Such electrostatic noise and electromagnetic interference make electronic equipment unable to work normally or even damaged.   Pay attention to:   The wristband should keep the body and the ground equipotential. ESD protection workbench should keep equipotential between device and ground. It is not allowed to place electrostatic insulating materials in the safe area .The circuit board with IC must be handled on the antistatic workbench. Wristbands and shoe covers should be tested every day to ensure that they meet the parameter requirements.   All instruments and equipment shall be grounded. Regard all components as electrostatic sensitive devices. Never touch sensitive devices or components without good grounding.   In the absence of other anti-static measures, do not take the IC installed in the anti-static tube. Use fixed-point ion eliminator in the process that may generate static electricity. If the IC is not on the process line or anti-static workbench, store them in a container with grounding shield. The gas and liquid flowing through IC should

Digital signage is a brand-new media concept. It generally refers to large-scale shopping malls, supermarkets, hotel lobbies, restaurants, airport subway stations, cinemas, and other public places where other people’s traffic converge. The large-screen terminal display equipment can release business information and finance. Multimedia professional audio-visual system with entertainment information. Its purpose is to broadcast advertising information to a specific group of people in a specific physical place and a specific time period, so that it has the effect of advertising. Overview The digital signage system is juxtaposed with paper media, radio, television, and the Internet, and is called the “fifth media.” composition The Digital Signage system consists of the following parts: ——Display terminal (LCD liquid crystal display) –media Player Support video: MPEG-1, MPEG-2, MPEG-4, DivX, Xvid, H.264, Quicktime, WMV, AVI, FLV Audio: MP3, WAV, AC3, AIFF Images: JPEG, GIF, PNG, TIFF, BMP, and image slideshows with page turning effects Flash animation: Flash 8, Flash 9, Flash 10 ——Management Software 1. Content management -Powerful browser interface for media content creation and management -Role-based account security control -Create new program types without programming -Each player can customize different playlists -Online preview of the designated player, the playlist of the designated time -Dynamic display content defined by XML -Support dynamic content data in RSS format 2. Advertising management -Each ad placement can include one or more media files -You can specify the number of times and the sequence of ads in each playlist -Support multiple media formats: AVI, FLV (Flash Video), Quicktime MOV,
