Outdoor high brightness LCD panel features 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 levels of ambient light. The brightness of these displays is measured in nits, and outdoor displays typically have brightness levels of 1500 nits or higher. Outdoor high brightness LCDs play an important role in outdoor advertising, public transport, stadiums, and other venues due to their high brightness, high contrast ratio, wide viewing angle, and durability. The following is a detailed analysis of the characteristics, technical principles and applications of outdoor high brightness LCD screen:
First, the characteristics
High brightness: the brightness of outdoor high brightness LCD screen is usually more than 1500cd/m², and can even reach 3000cd/m² or higher. This makes the screen in direct sunlight outdoor environment can still maintain a clear and visible display.
High Contrast Ratio: This type of LCD screen has a high contrast ratio, generally above 1000:1, which makes the display content clearer and more distinctive.
Wide viewing angle: outdoor high brightness LCD screen using special liquid crystal materials and drive technology, to achieve a wide viewing angle of more than 170 degrees horizontally and vertically, to ensure that the display effect in a variety of angles when viewing.
Energy saving and environmental protection: LED backlight technology, with low power consumption and high service life, is conducive to energy saving and emission reduction.
Second, the technical principle
The principle of outdoor high brightness LCD liquid crystal screen is to use the transmittance of liquid crystal, through the combination of liquid crystal unit 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 will be deflected, changing the direction and intensity of the light, thus realising the display of images. In addition, the high-brightness LCD uses a high-brightness LED backlight to provide brighter and more vivid images.
Third, application area
Outdoor advertising: Outdoor high brightness LCD screen is widely used in outdoor advertising areas, such as bus stops, underground stations, commercial areas and so on. Its high brightness and high definition can attract people's attention and enhance the advertising effect.
Public Transportation Stations: With the use of high brightness LCD screens on bus stops, passengers can still see the information clearly under direct sunlight.
City facilities: High brightness LCD screen is also widely used in all corners of the city, such as charging piles, petrol stations, self-service enquiry machines, electronic newspaper reading boards and so on.
Corporate institutions: high brightness LCD screen has also entered the corporate institutions, become the Telecommunications Bureau, Tax Operations Bureau, banks and hospitals, and other places of self-help query the right hand.
Fourth, with the use of touch screen application advantages
With the increasing demand for mobile devices in outdoor environments, touchscreens equipped with high-brightness displays have become a popular and essential choice for many industries.
Touchscreens equipped with high-brightness displays provide a superior viewing experience in bright sunlight. The high brightness feature keeps the display visible in direct sunlight, ensuring that users can operate their devices 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 for use 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.
