09/14/2022As the research and development of electronic application equipment technology become more and more mature, many new lifestyles and working media are undergoing earth-shaking changes. These technologies have inadvertently touched every corner of society so that we often say that the world’s rhythm is changing too fast!
In the traditional concept, information media generally use paper tools as the carrier of news or advertising, but it is clear that these media have fallen behind in today’s information explosion era. Today’s news and media use more colorful pictures and Well-made videos are used as content presentation methods, in order to output more high-quality content in a short time!
The advent of LCD displays largely solves the problem of disseminating more content and information in a relatively short period of time. You can see LCD monitors on many channels such as subway entrances, elevators, outdoor billboards displayed the content of media content. However, there are many styles and types of LCD display screens, and not all LCD monitors are suitable for the transmission of rich media files, especially in the case of strong external ambient light. Because the high-brightness external environment will seriously affect the normal display of the content on the LCD monitor.
Fortunately, advances in technology have gradually made the impossible in the past possible. High Brightness Monitor adopts a unique design principle, so that rich media content on the screen can be clearly displayed in a high-brightness external environment, even if the sun is directly on the LCD display without any problems. Some people may not know the working principle and technical composition of High Brightness Monitor, so let’s explain this problem in detail first.
A high brightness monitor, also known as a sunlight readable monitor or VHB (very high brightness) monitor is a computer monitor designed to operate in very bright environments, for example in broad daylight. Sunlight Readable monitors typically provide at least 1,000 nits of brightness, versus 200-300 nits brightness for a typical desktop computer monitor. Sunlight Readable monitors may also be optically bonded. This process adds a protective outer glass, then fills the air gap between the glass and the LCD panel with an optical-grade resin to eliminate internal reflections and condensation. This also strengthens the outer glass and improves image contrast.
High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
Nit is the unit of brightness, 1nit=1 cd/m². Brightness refers to the physical quantity of the intensity (reflective) of the surface of the luminous body (reflector). The human eye observes the light source from one direction. The ratio of the light intensity in this direction to the area of the light source “seen” by the human eye is defined as the unit brightness of the light source, that is, the luminous intensity per unit projected area. The unit of brightness is candela/square meter (cd/m2). Brightness is how people feel about the intensity of light. Luminance refers to the degree of brightness and darkness of an object. It is defined as the luminous intensity per unit area. The unit is nit. 1 nit = 1 Cantera/square meter. Lumen (LM) is the unit of luminous flux. Through the above specific term explanation, we know that High Brightness Monitor and ordinary LCD monitors are not particularly technically different. The biggest difference is that the number of nits is much higher than that of ordinary LCD monitors. So why does High Brightness Monitor have such a special function? We need a technical explanation from its special structure
High brightness monitors are used in uncontrolled lighting environments, we add customized passive enhancements to maximize the contrast and brightness of the touchscreen interface. Anti-glare coating on the face of the touchscreen, and anti-reflective coating on both sides of the LCD. These coatings mirror the index of refraction to reduce light reflecting back at the operator which enhances overall readability and increases the contrast ratio in high direct light and high ambient light environments.
A normal LCD will turn black when exposed to sunlight and UV radiation. Design innovations allow the LCD to operate in direct sunlight. Through the use of these special coatings, films, and filters, the unit obtains sunlight readability without additional backlights. The end result is 1000+ nit equivalent viewing without the additional power draw and heat generation of more backlights. Consequently, our flat panel display systems have longer life, better processor performance, and wider operating temperature range.
In order to make a high brightness monitor with low energy consumption and high display contrast, Yousee company uses LED strips instead of CCFL as the backlight source. Coupled with the optical enhancement of the lighting film, prism diffuser and lighting system, the brightness can be increased to 2000 nits through a low-power backlight. As the brightness of the backlight increases, the color saturation is also improved, and it provides better uniformity, better optical performance and visibility for all objects under bright daylight conditions. With our advanced LED backlight design, Yousee company can achieve excellent energy-saving effects for the high brightness monitor solution; compared with competing products with the same brightness level, it saves about 18.6%. For example, a 17-inch, 1000-nit ordinary LCD monitor usually consumes 32W, while Yousee’s high-brightness solution consumes only26.53W.
DIFFERENT TYPES OF HIGH BRIGHTNESS MONITOR
Elevator advertisement High Brightness Monitor
Because the elevator waiting time is relatively long and boring, and often meet strangers when taking the elevator, in order to avoid embarrassment between each other, the elevator space has become a good place for advertising. Elevators are generally deployed in high-rise buildings. These places are usually illuminated by bright external light. If ordinary LCD monitors may not achieve the normal rich media content display effect, but when using High Brightness Monitor, there is no such problem.And because of its professional content display effect, it will bring a pleasant feeling to the elevator ride.
ShoppingMall advertisement High Brightness Monitor
As the most competitive place in shopping malls, the emergence of High Brightness Monitor is of course indispensable. All kinds of beautifully-made advertisements are too outdated if they can only use paper propaganda posters to convey the content. This is to be laughed at by other business competitiver. Especially for some famous brands, they use High Brightness Monitor not only to sell their products, but also to promote their brands and further improve their brand awareness. These brands may use the form of new product launch conferences or some other promotional methods to show their media content. These contents are often dynamically changing, so without the help of High Brightness Monitor, the final effect may be greatly reduced!
Parking lot advertising high brightness monitor
You may wonder why the parking lot needs High Brightness Monitor? Isn’t the time people staying in the parking lot very short? In fact, the real situation is not like you think. According to relevant data surveys, many people choose to sit quietly in the car during the period between parking and going home. It may be because of the fatigue of long-distance driving and the need for a certain rest time, or it may be that the daytime work is not satisfactory and needs to be adjusted emotions, or need a good reason for forgetting to buy gifts for family members (of course, this is a joke). In short, more and more underground parking lots put High Brightness Monitor for advertising and other multimedia content as a channel and method of publicity. And the effect achieved by this method is also very good. Judging from the increasing number of High Brightness Monitor in underground parking lots, this method will become a very popular method in the near future!
Outdoor Exhibition High Brightness Monitor
With the advancement of technology, many traditional masterpieces can be displayed in the form of electronic media, such as Leonardo da Vinci’s Mona Lisa, Van Gogh’s Sunflower, Picasso’s Avignon Girl; although these electronic works are not compatible with The real works are comparable, but the details are sufficiently fake. Art works should not be shelved but should be let more people understand and appreciate, but the original works are unique and there is no possibility of copying. If they are displayed at random outdoors, they are easily damaged and destroyed, so the emergence of High brightness Monitor can be very A good solution to this problem. Scanning and restoring the original paintings through electronic equipment will show these rare treasures to the greatest extent in front of ordinary people, so that these precious art treasures can step down the altar and blend into the environment where ordinary people appreciate beautiful works! Since then, whether it is day or night, whether it is sunny or rainy, High Brightness Monitor can give ordinary people the opportunity to appreciate famous paintings anytime, anywhere!
