Indoor LED electronic display how to prevent glare
Consumers who often use LED electronic display screens will find that the LED electronic display screens used in hotel conference rooms will cause burns to the eyes when viewing them for a long time. When the TV program is recorded, the content of the LED electronic display is switched too fast, and the brightness changes too fast, which will also make the audience off the field feel very uncomfortable. Some low-quality indoor LED electronic displays can even cause symptoms such as dryness, tearing, and blurred vision. This is why the indoor LED electronic display not only brings us clear picture quality and brilliant color display effect, but also brings the glare that is harmful to the eyes.
The glare index is an index to predict and evaluate the uncomfortable glare condition of indoor working environment. According to the mechanism of glare formation, glare of LED electronic display can be divided into two types: direct glare, which is caused by the high brightness of the LED electronic display and the strong directionality of the LED light source; reflective glare, which is caused by some The high reflection coefficient of the surface of the LED electronic display material is caused by the strong reflected light of other light sources.
Indoor LED electronic displays are generally used in hotel conference rooms, stadiums, live TV, concerts and other occasions. In the case of long-term viewing within a short distance of the human eye, the human eye will be stimulated by the direct glare of the LED electronic display. When the pupil is narrowed, the eyes will feel obviously uncomfortable, and long-term viewing will cause damage to the human eye.
The most direct way to prevent direct glare is to reduce the brightness of the LED electronic display, but while reducing the brightness of the LED electronic display, it also loses the core advantage of the indoor LED electronic display – grayscale, the difference between the two. Gaming is also one of the key thresholds for “low brightness and high gray” indoor small-pitch LED electronic displays.
In addition to its self-illumination, the glare of the LED electronic display screen is also partly caused by the reflection of the strong light in the surrounding environment on the surface of the LED electronic display screen material. Especially the LED stage background screen, the reflection glare is particularly serious. For the prevention and control of such glare, the choice of reflective material is mainly considered.
While paying attention to the quality of LED products, the safety and health of LED products, the indoor LED electronic display using surface-emitting devices is the most representative eye protection product in the LED display industry at present. Through the surface luminescence technology and surface atomization treatment technology, the light emitted by the LED lamp beads is soft, natural and not harmful to the eyes, and at the same time, the reflection glare of the LED electronic display screen is reduced, and the dazzling phenomenon of the indoor LED electronic display screen is greatly improved. , achieves the effect of effectively protecting the eyes from damage and completely eliminating point light sources.
In the era of indoor small-pitch display and smart life, LED electronic displays must not only be colorful and have a long service life, but also take into account the safety and comfort of the viewer, and a healthy screen can be closer to consumers.
