Display | awe Electronics | indoor led display provided by the awe-inspiring electrons. _ _ Awe-inspiring display electronic display prices is three, full-color LED display full color LED display to identify good and bad Tai'an City awe Electronics Co., Ltd. (www.tahrdz.com) 2014 has been newly upgraded launched mainly from the following signed several aspects: 1. The flatness. LED display surface flatness to within ± 1mm, in order to ensure that the displayed image is not distorted, partial raised or recessed causes the display viewing angle appears dead. Flatness is good or bad is determined mainly by the production process. 2. brightness and viewing angle. Indoor full color brightness to the 800cd / m2 or more, and outdoor full color brightness to display the 1500cd / m2 above price, in order to ensure the normal operation of the display, otherwise it will be too low and can not see because of the brightness of the displayed image. The size of the brightness of the LED lamp is good or bad decision. LED directly determines the size of the viewing angle of the display how much of the audience, and therefore the bigger the better. Mainly by the size of the viewing angle die packages to decide. 3. The balance effect. White balance is one of the most important indicators of the LED display. The proportion of red, green and blue color science taken as 1: 4.6: 0.16 When will exhibit pure white screen, if the actual proportion of the white balance a little deviation deviation occurs, usually pay attention to whether there is bluish white, yellowish green phenomenon. White balance is mainly determined by the quality of the LED display control system, lamp beads for color reduction is also affected. 4. The color reduction. Color reduction refers to the reduction of color LED display on the electronic display, color LED display shows both to be highly consistent with the source of the color, so as to ensure that the image of realism. Outdoor LED display is not loaded on several reasons when using outdoor LED display, often phenomenon can not be loaded. Electronic LED display manufacturers from Britain to analyze several aspects of the following under the LED display on the reasons for not loaded. 1. Check the jumper cap is loose or fall off; if the jumper is no loosening, make sure the jumper in the right direction. 2. Check to make sure the serial cable is used to connect the controller to direct line, not a crossover cable. 3. Check to make sure that the serial cable is intact and no loose ends or off phenomenon. 4, the control LED display control software and control card they choose to use to select the correct product model, the correct transmission, the correct serial number, correct serial transmission rate and controls within the software properly set DIP switches Figure address bits, and the serial transmission rate control system hardware. 5. Ensure that the control system hardware has the right power. 6. If the above checks and still not load after correction, use a multimeter to measure the indoor led display, PC or control system is connected to the serial port hardware is damaged. To confirm whether computers should be returned to manufacturers or to return control system hardware testing. In short, LED display abnormal loads reason, it may be the product itself, is also possible that you are in the process of using improper operation caused. As long as careful thought or asked to find manufacturers, it is easy to find the root of the problem.
