how to fix stretched out screen on windows

LCD mainly consists of LCD black-and-white screen and TFT color screen. The following mainly introduces the relationship between the manufacturing difficulty and size of LCD black-and-white screen: According to expert statistics, the size and process difficulty of LCD segment code screen have such a rule: the larger the size, the more complex the manufacturing process. The main reasons are as follows:   The larger the size of LCD, the more difficult it is for staff to operate.   The larger the size of LCD is, the higher the requirement of equipment grade is.   The larger the size of LCD, the higher the defect rate of the product.   The larger the size of LCD, the more bad things will appear, such as darkening.

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.
