Outdoor high brightness LCD panel characteristics and application analysis
Outdoor high brightness LCDs, as the name suggests, have higher brightness and visibility. They are designed for use in outdoor environments where there is sunlight and high ambient light. The brightness of these displays is measured in nits, and outdoor displays are typically 1500 nits or higher. Outdoor high brightness LCD displays play an important role in outdoor advertising, public transport, stadiums and other venues due to their high brightness, high contrast, wide viewing angle and durability. The following is a detailed analysis of the characteristics, technical principles and applications of outdoor high brightness LCD:
1. Features
High brightness: the brightness of outdoor high brightness display is usually above 1500 nits, and can even reach thousands of nits, far beyond the ordinary display. This high brightness design ensures that the content can still be clearly displayed under direct sunlight, avoiding the problem of illegible screen content caused by too much light.
High Contrast Ratio: This type of LCD screen has a high contrast ratio, usually above 1000:1. The high contrast ratio makes the images and text clearer and enhances readability in bright light environments. Even in outdoor environments with complex lighting, users can easily recognise the information on the screen.
Wide viewing angle: outdoor high brightness LCD screen using special liquid crystal materials and drive technology, to achieve horizontal and vertical 170 degrees above the wide viewing angle, to ensure that the display effect when viewed at various angles.
Energy saving and environmental protection: LED backlight technology, low power consumption, long service life, is conducive to energy saving and emission reduction.
Anti-glare coating: Some outdoor high-brightness displays are also equipped with anti-glare coating, which effectively reduces the impact of reflected and diffused light on the screen and improves visibility. Even under direct sunlight, users can get a clear visual experience.
2. Technical principle
The principle of outdoor high brightness LCD screen is to use the transmittance of liquid crystal, through the combination of liquid crystal units to control the direction and intensity of light, so as to achieve the image display. Liquid crystal unit consists of multiple liquid crystal molecules, each liquid crystal molecule can control the direction and intensity of light. When a voltage is added to the liquid crystal unit, the liquid crystal molecules are deflected, changing the direction and intensity of the light to achieve image display. In addition, high-brightness LCDs use high-brightness LED backlighting to provide brighter and more vivid images.
3. Application Areas
Advertising Media: Outdoor high brightness display is suitable for various outdoor billboards, bus stops and other scenes. Its high brightness and wide viewing angle design can attract the attention of pedestrians and improve the exposure rate and dissemination effect of advertisements.
Public transport: Installing outdoor high brightness displays at bus stops and underground platforms can provide passengers with real-time traffic information. Its high brightness and wide viewing angle design ensure that passengers can clearly see the information content at different angles.
Commercial display: Scenes such as shopping mall windows and exhibition displays are also suitable for outdoor high brightness display. It can attract customers' attention and increase the exposure and sales of goods.
Other fields: outdoor high brightness display is also widely used in handheld terminals (such as handheld code scanners, handheld laser rangefinders, etc.), intelligent rubbish sorting station indicator screen, farmland monitoring and other fields, providing convenient solutions for different industries.
4. Outdoor high brightness display and touch screen with the use of application advantages
With the growing demand for mobile devices in outdoor environments, touchscreens equipped with high-brightness displays have become a popular and essential choice for many industries.
Touchscreens with high-brightness displays provide a superior viewing experience in bright sunlight. The high brightness feature makes the display visible in direct sunlight, ensuring that users can operate the device efficiently regardless of the outdoor environment. This is especially important for industries such as construction, transport and agriculture where equipment is operated outdoors.
Touchscreens with high brightness displays also increase safety when used in outdoor environments. For example, in the transport industry, drivers can operate navigation systems or check the status of their vehicles without being distracted by glare or reflections. This reduces the risk of accidents caused by distracted driving.
