Technical progress in LCD splicing screen size and seam

From the demand of the commercial display market, LCD splicing screens are subject to more competition in the fields of education, security, engineering, digital signage, etc. Therefore, while the technology is highlighted, the LCD display is meticulously crafted and can break the small The size of the application is limited, focusing on the LCD splicing display products to achieve a “seamless” display effect in the splicing gap, as well as the further large-scale and diversified size, and the technical experience of high-definition highlight display. The LCD splicing screen is composed of multiple unit screens. Each splicing unit has a long life and low radiation to support its stable performance to support it. Different processing systems can be selected according to the user’s requirements for input signals. Supported by the application of emerging technologies, it can smoothly access massive signal sources and receive remote signals, which is conducive to the free switching of various signals through the control software, splicing into full-screen display, arbitrary combination display, image roaming and superimposing display, etc. , Such as can make it fully cope with the multi-faceted display system application of remote data roaming monitoring in the security field. It is enough to witness that such an ultra-high application solution can create personalized use for users on different occasions, and meet the needs of big data computing in the new era! The application of LCD splicing screen display is based on its excellent advantages in terms of diversified display methods and carrying massive signal reception

LCD touch screen cannot work, touch no response how to deal with

[Fault Phenomenon] One LCD touch screen doesn’t work, and there is no response when touching any part.   [Fault Analysis and Treatment] First check whether the connection interface is loose, and then check whether there is conflict between serial ports and interrupt number. If there is conflict, adjust resources to avoid conflict. Then check whether there are cracks on the surface of the touch screen. If there are cracks, replace them in time, Also need to check whether there is dirt on the touch screen surface, if there is, use a soft cloth to remove it. Observe and check whether the indicator light on the control box works normally. When it works normally, the indicator light is green and flashes.   If the above parts are normal, the touch screen can be checked by replacement method, first replace the control box, then replace the touch screen, and finally replace the host.   If it is a resistive touch screen, it can be overhauled as follows: 1)Check whether the connection of the touch screen is right, and whether one of the connections (taking 5V touch screen working voltage from the keyboard port) is connected. Please check the connection. 2)Observe the light condition of the touch screen control box. If it doesn’t light up or the red light is on, the control box is broken. Please replace it. 3)If not, please delete the touch screen driver and restart the computer, re-install the driver, or replace the driver with a newer version. 4)If

The development of LCD touch Screen

With the increase of information inquiries from multiple TV stations, many people are talking about LCD touch all-in-one. As a newest PC input device, it is the simplest, convenient, natural and suitable for China’s multiple TV stations. The input equipment for querying national conditions has many advantages such as sturdiness and durability, fast response speed, space saving, and easy communication. In order to facilitate the operation, many people use LCD touch all-in-one computers to replace the mouse or keyboard. When working, we must first touch the screen installed in the front of the display with our fingers or other objects, and then the system locates and selects information input according to the icons or menu units touched by the fingers. The liquid crystal touch all-in-one machine is composed of a touch detection component and a controller; the touch detection component is installed in front of the display screen to detect the user’s touch position and take over and send the controller; and the primary function of the controller is to absorb the touch point detection assembly Touch the information and convert it into contact coordinates, and then send it to the CPU. It can also absorb the commands sent by the CPU and execute them. The touchpad uses pressure-sensitive capacitive touch technology, with the largest screen area. It consists of three parts: the bottom layer is the middle sensor, which is used to monitor whether the touchpad is High plastic material composition. The growth of LCD touch all-in-one technology shows
