How to Choose High Quality TFT LCD Screen? --OLED Display Screen Manufacturer
TFT anti-glare high-brightness liquid crystal display can see the display content in the sunlight. It is coated with a special coating on the screen surface to make the display screen have anti-glare function. TFT-LCD is a thin-film transistor LCD display, which is called "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel. Each pixel can be directly controlled by a point pulse, so each node is relatively independent and can be controlled continuously. It not only improves the reaction speed of the display screen, but also can accurately control the display color order, so the color of TFT liquid crystal is more true.
The value of the product is determined by the brand of liquid crystal glass. Generally, the manufacturers of high brightness TFT liquid crystal screen mainly choose LG liquid crystal glass. Of course, other can also be, mainly for each brand of large-size liquid crystal glass heat resistance is different, there are some price gaps. So how do we choose a high quality TFT LCD screen?
The uniformity of backlight of high-brightness TFT LCD screen can only reach 65%-75% in general manufacturers, 75%-85% in good manufacturers and 90%-95% in point type. Of course, the price of a good high-definition screen is different.
The brightness of high-brightness TFT LCD screen is generally high, but it is soft and not dazzling. It is not equal to the illumination of backlight. The brightness value is a color circumference value, which is related to the color saturation, contrast and illumination of backlight. So looking at a very bright screen does not necessarily achieve the brightness we need, because the human eye sees that illumination, illumination by the environment, space size, and other aspects of the impact of the instrument is measured brightness.
A good high-brightness TFT LCD screen produces low power and low heat dissipation. The core of this is the packaging process of LED backlight and the application of light efficiency. The process is not up to standard and the light efficiency is not up to standard. The higher the heat may be emitted by the high-brightness TFT LCD screen, the higher the heat dissipation technology is needed to reduce the temperature of the backlight to ensure the LED backlight. Normal use of light.
But this one only solves the problem of backlight, and has not solved the problem of high temperature of liquid crystal glass at all. The high-brightness screen is only a semi-finished product. It is a source of heat in itself when used outdoors. So at present, there will be enterprises on the market to add aluminium profiles on the back cover of the screen, (change direction through heat conduction to heat dissipation), and the labeling is not cost-making.
In other words, the most important part of a good high-brightness screen is the backlight technology, not the heat dissipation in the external structure. A good backlight technology can achieve the required color temperature range, high color saturation, high contrast, high uniformity, high brightness and non-dazzling, and control the influence of the heat emitted by the LED backlight on the liquid crystal glass. Most importantly, the higher the temperature, the greater the light decay of the LED backlight, and the shorter the service life.
How to choose a high-quality TFT LCD? High-quality TFT LCD screen is not only a good light source, light selection beads, packaging process is not good, light source is good, LED heat dissipation process is not good, light guide process is not good, light efficiency is not good, so when choosing a good high-brightness LCD screen, we must pay attention to whether the manufacturer is professional.
