The demand for outdoor LCD displays is growing stronger.
More and more end products are using outdoor LCD displays.
This article will introduce the five elements of selecting outdoor LCD displays,
so that everyone can better understand how to properly choose outdoor LCD displays.
Generally, the brightness of an outdoor LCD display is high, but it is softer and not glaring.
It is not equivalent to the illumination of the backlight.
The brightness value is a color circumference value that is related to the color saturation of the panel being made, the contrast, and the illumination of the backlight.
Therefore, looking at a very bright screen does not necessarily achieve the brightness value we require, because the human eye sees the illumination, the illumination is affected by the environment, the size of the space, and other aspects.
The brightness measured by a professional instrument is the brightness.
High-quality outdoor LCD displays not only need to choose a good light source, but also need to choose a good lamp bead and a good packaging process.
Therefore, when choosing a good outdoor LCD display manufacturer, we must pay attention to whether the manufacturer is professional.
Pay attention to temperature when purchasing an outdoor LCD display.
The products produced by good outdoor LCD manufacturers have low power and low heat dissipation.
The main reason is that the core is the packaging process of LED backlight and the application of light efficiency.
If the process is not up to standard, the light efficiency will not be improved, and the heat generated by the high-brightness screen may be increased.
At the same time, the technical cooperation of heat dissipation is needed to reduce the temperature of the backlight to ensure the normal use of the LED backlight.
But this piece only solves the backlight and has not solved the problem of high temperature of the liquid crystal glass.
The outdoor LCD panel is only a semi-finished product.
It is a source of heat itself. Therefore, there are factories on the market that add aluminum profiles to the back cover of the screen (the heat is dissipated through heat conduction) but it still cannot solve the essential problems.
The most important aspect of high-quality outdoor LCD displays is the backlight technology, rather than the heat dissipation of the external structure.
The good backlight technology can achieve the required color temperature range, high color saturation, high contrast, high uniformity and high.
The brightness is not glare, and the effect of the heat emitted by the LED backlight on the liquid crystal glass is controlled.
The most important point: the higher the temperature, the light decay of the LED backlight, and the shorter the
4. The Uniformity Of The Backlight
the uniformity of the outdoor LCD display of the general outdoor LCD display manufacturers may only reach 65%-75%,
the uniformity of the good manufacturers can reach 75%-85%, and the uniformity of the backlight of the high-quality outdoor LCD display manufacturers can be It reaches 90%-95% or more.
Of course, the price of a good outdoor LCD display is different.
The main brands of commercial outdoor LCD displays are LG, Samsung, AUO, Innolux, BOE.
JFCVision outdoor LCD display manufacturers mainly choose to use these large brands of LCD glass. To ensure the stability of the outdoor LCD displays.
