Technology is changing our life. Our phone upgrade rapidly, it is more like a palmtop rather than a communication tool. Our computer turn into a pad from enormous one. Our television become more slim than before. …… All of these tells us a truth that you have to change when things change. Now, our products also get a reform from advertising display into a part of monitoring system. Ten years ago, some told you that monitor can help traffic police to take a picture, we may laugh at him. But now, it just a normal function of monitoring system.

Nowadays, more and more people choose outdoor lcd display as their first choice when they are about to promote products.   Instead of poster and light box, outdoor lcd products become popular in these years. Therefore, we would like to share the reason why the public prefer outdoor lcd display rather than poster or light box.  With the development of our modern society,the birth rate of developed countries has decrease year by year. Even worse, some countries have nagative growth in population.In response to the expensive labor power, more and more people choose outdoor lcd digital sinage to reduce their budget other than poster or light box. No matter who you are, where you in, globlization has great impact on us. To be or not to be, it is not just a slogan. What is water to the fish, what is outdoor lcd display to you.

Eight advantages of liquid crystal display 1) low voltage and low power consumption Very low operating voltage, as long as the 2V~3V can work, and the operating current is only a few a few characters that are only a few characters. A small button battery can also be used for 1~2 years, which is unmatched by any other display devices. Liquid crystal display is compatible with the development of large scale integrated circuit at operating voltage and power consumption. Such as electronic watches, calculators, portable instruments, portable computers and GPS electronic maps, etc.. Low voltage drive General twisted nematic (TN) device threshold voltage is only 1.5~2V, can be directly integrated with large scale integrated circuit. 3) flat plate structure The basic structure of the liquid crystal display device is a thin box made of two glass substrates. This structure is most conducive to the display window, and it can accommodate the largest amount of display content in a limited area, the highest utilization of display content. In addition, the structure can be made very small, such as the display window used on the camera, and a great deal, such as large screen LCD TV and large LCD billboards. This structure is also convenient for high-volume, automated production. At present, the production of liquid crystal display (LCD) devices is mostly produced by the integrated process of automation and semi automation. Only a small number of workers can start a production line of thousands of years. At present, the liquid crystal display device has been developed. The device is as thin as paper and can be bent, thereby further reducing the use of space. Passive display A, indicating that the device itself can not light, it depends on the modulation of external light to achieve the purpose of display. It is not as active as the display device, by the light to stimulate the human eye to achieve the display, but simply rely on the different reflection of the external light to form the different contrast to achieve the purpose of display. So called passive display. Passive display is more suitable for human vision, not easy to feel tired. This advantage is particularly important in the display of large amounts of information, high density, fast transformations, and long observations. B, passive display is not afraid of light erosion. The so-called light erosion, is refers to when the ambient light is bright, the displayed content information is light diluted to display is not clear, and the passive type display, because it is by the external reflection lidar to display purposes, so the external light is strong, the reflected light is stronger, the content displayed is more clear. C, liquid crystal display can not only in the outdoor can also be displayed in the interior, in the interior of the dark display can be equipped with backlight can overcome the shortcomings can not be seen. 5) display a large amount of information Compared with CRT, a liquid crystal display device without shadow mask restrictions, pixels can be made smaller, more fine; compared with the plasma display, liquid crystal display pixel without plasma display, leaving the isolation zone between pixels to a certain. LCD display in the same size of the display window area, can accommodate more pixels and more information, which for the production of high-definition TV, notebook computers are very favorable. Easy colorization There is no color in the liquid crystal, and there are many ways to achieve color, such as color filter and interference. Due to the color filter technology is more mature, so that the color of the liquid crystal is more accurate and more beautiful color in the color distortion effect. Long life The liquid crystal material is organic polymer materials, high purity, other materials are made of high pure substances in purification conditions, the driving voltage of the liquid crystal is very low, the drive current is very small, almost no deterioration of the device, life is very long, from the perspective of practical application, in addition to hard hit, broken or damaged parts, liquid crystal display, its life is almost no end. No radiation and no pollution Liquid crystal display device in use will not produce soft X ray or electromagnetic wave radiation, and radiation can cause environmental pollution and information leakage, and liquid crystal display device does not produce such problems. It is an ideal display device.

OLED display screen is made of organic electroluminescent diode. At the same time as with self luminous, without back light, thin, high contrast, wide viewing angle, fast response, and can be used for flexible panel, wide temperature range and relatively simple structure and process and other excellent properties, is considered to be the next generation of flat panel display new application technology. OLED is self luminous materials, does not require backlight, also wide perspective, quality uniform, fast response, easy color, simple drive circuit to achieve the light, the preparation process is simple and can be made into a flexible panel, with shorter principle, application scope belongs to small and medium size panels. Display: active lighting, wide viewing angle, fast response, stable image, high brightness, rich colors, high resolution. Working conditions: low drive voltage, low energy consumption, can be matched with solar cells, integrated circuits, etc.. Wide adaptability: the glass substrate can be used to achieve large-area flat panel display, such as flexible material as substrate, can be made into a collapsible display. Since OLED is a solid state, non vacuum device, with the characteristics of earthquake resistance, low temperature (-40 degrees C) and so on, it has a very important application in the military field, such as the display terminal of modern weapons, such as tanks, aircraft and so on.
