How to distinguish and apply LCD liquid crystal screen and LED display screen


At present, LCD screens and LED displays are widely favored by users. Many users do not know how to distinguish the particularity of the two products and the screening of application fields, and which display screen should be selected. Senior technical engineers of United Huiye Technology here Systematically analyze the respective advantages and disadvantages of LCD liquid crystal screen and LED display screen in detail for everyone, so that users can have a deeper understanding and understanding of the choice of LCD liquid crystal screen and LED display screen application fields. First of all, it mainly depends on the application site of Party A. A very important factor for indoor and outdoor applications is the change of ambient light (that is, the demand for brightness). Human eyes are very sensitive to brightness. If the indoor light is weak, the brightness of the display screen will be correspondingly low. Some, semi-outdoor or outdoor sunlight has a greater illuminance, so the brightness factor should be considered when choosing a screen. According to internationally recognized standards: viewing with a brightness exceeding 700cd/㎡ will cause damage to human eye health, and outdoors due to high direct sunlight illumination, the brightness of the outdoor LED display screen must be at least higher than the illumination, so that the human eye can see the display. screen. The brightness value of LCD liquid crystal splicing screen is between 450 cd/㎡ and 700 cd/㎡. The brightness is uniform and the color saturation is high, which can better achieve the best viewing effect of the human eye. The LCD splicing screen is composed of single or multiple liquid crystal display units, and the splicing methods are various and arbitrary. By controlling the image controller, any combination of display mode switching and signal switching can be realized, which meets the needs of indoor places such as meeting rooms and monitoring rooms. For the different needs of the display screen, there is a disadvantage that the LCD splicing screen will have a dividing line when splicing larger screens. This is a problem that cannot be solved at present. High-end technicians are looking for a solution to this problem. The LED display has strong luminous brightness, and the display screen is still clearly visible when the sun shines directly on the screen. The function of automatically adjusting the brightness of the LED screen can obtain a good playback effect under different brightness environments, so it can be used indoors and outdoors. Another point of LED is to use Self-luminous display technology, the screen brightness is generally very high, through the brightness adjustment setting, it can work for a long time and prolong the service life. Compared with LED LCD screens, LED display screens have longer life, faster response speed, and lower energy consumption. LCD splicing screens adopt "image vertical adjustment technology" with a viewing angle of more than 178 degrees, which is wider than LED display screens. How to make a choice between LCD splicing screen and LED display mainly depends on the needs of the user's own application site and the recognized brand. Shenzhen Lianhuiye Technology Co., Ltd. and its technical team independently research and develop technology to continuously produce cost-effective LED display products. , Product quality, pre-sales and after-sales service, product quality and many other aspects have won unanimous praise from users. .
