Advantages and precautions for use of small-pitch LED display

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology. The large screen used for more than one or two years can be used to perform a one-time calibration of the entire screen. The operation process is simple and the effect is very good. When using a small-pitch LED display, pay attention

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

China to strike harder against regions that fail to curb energy use

Dear Customer, Perhaps you have noticed that the recent “dual control of energy consumption” policy of the Chinese government. China will toughen punishments for regions that fail to meet targets aimed at controlling energy use, the state planning agency said in new policy guidelines published on Thursday (16th Sep 2021). China has been cracking down on high-energy consuming projects after 20 of its 30 provinces and regions failed to meet energy consumption targets in the first half of the year. In addition, the China Ministry of Ecology and Environment has issued the draft of “2021-2022 Autumn and Winter Action Plan for Air Pollution Management” in September. This autumn and winter (from October 1, 2021 to March 31, 2022), the production capacity in some industries may be further restricted. This step would have a certain impact on the production capacity of some manufacturing companies, and the delivery of orders in some industries has to be delayed. To mitigate the impact of these restrictions, we recommend that you place an order as soon as possible. We will arrange production in advance to ensure that your order can be delivered on time. If you have any questions, please contact us and we will respond to you as soon as possible.
