What Is Sunlight Readable Display?

In outdoor industrial applications, the problem of strong direct sunlight is often faced. Ordinary display screens are difficult to see clearly under direct sunlight. Why are screens hard to see in sunlight? In this environment, the sun's brightness is higher than the industrial display's, and the image on the screen will be diluted. To solve the display problems of traditional displays under sunlight, sunlight readable displays are an ideal solution for outdoor industrial environments.

What do you know about readable displays in the sun? Do you know how to see screen in sunlight? Do you want to know their advantages and applications? This article covers everything you need to know about sunlight readable displays. So, let's get started!

What is sunlight readable display technology?

Sunlight readable displays are a display technology specifically designed for outdoors and in environments with strong sunlight exposure. Unlike traditional displays, sunlight readable outdoor displays offer better visibility and readability. Even in bright outdoor sunlight, people can still see the image on the screen.

How sunlight readable displays work?

How do sunlight readable displays work? To figure out how sunlight readable works, you must first understand the definition of visibility. Visibility is the degree to which an observer can recognize and perceive a target object or scene under certain conditions. In other words, visibility is linked to contrast, the variation in brightness or color between the object being observed and its surroundings. A sufficiently high contrast ratio can make an object visible against the background, while the opposite may result in blurring or difficulty in recognizing it. Therefore, for a display to be readable in sunlight, the brightness of the LCD needs to exceed the intensity of the light reflected from the surface of the display.

What makes a display sunlight readable?

After understanding how sunlight readable displays are designed, Advanvision has developed several techniques and technologies to improve the visibility of LCDs in sunlight. Below are some common technologies used to make LCDs visible in sunlight. Let's take a look!

High Brightness Panels

Sunlight readable displays utilize LCD panels with high brightness capabilities. LEDs provide a more powerful light that can produce a brighter image. Then the display can still provide a bright enough lightness in direct sunlight to ensure the image is visible. Generally, LCDs become high brightness sunlight readable displays when the screen's brightness increases to approximately 800-1000nites. However, such high brightness sunlight readable displays tend to require more power to emit more light, which can lead to greater power consumption.

Anti-Reflective (AR) Coatings

Sunlight readable displays can also use anti-reflective coatings to reduce or block light reflected from the sun. This type of LCD relies on surrounding light to illuminate the screen. These coatings allow more ambient light to pass through the screen rather than reflecting light. It can effectively minimize the reflection of light, allowing the user to see the image on the screen more clearly and reduce glare. The brightness of this LCD relies on the brightness of sunlight. As the sunlight gets brighter, so does the reflected brightness to the viewer's eyes. Therefore, this LCD can achieve 100% sunlight readability and has the feature of maximizing sunlight readability at the lowest energy cost. However, it is worth considering that since the display's lightness no longer competes with sunlight, the reflected light will also be weaker in low-light conditions, and the LCD will look less bright.

Optical Bonding

Optical bonding is a technology that applies a layer of adhesive between the LCD panel and the protective glass or cover. Since there is a tiny air gap between the touch screen and the display, it can cause specular reflection and interference with light transmission, reducing the display's visibility. So an adhesive is used to fill these gaps between the monitor and the touch screen through optical lamination technology. This technique eliminates the air gaps between the monitor and the touch screen, reducing reflections and scattering. This results in improving the clarity and contrast of the LCD monitor.

What are the advantages of a sunlight readable display?

So why should you choose sunlight readable displays? What are the benefits of sunlight readable displays for your business? Listed below are the benefits of sunlight readable displays.

Provides excellent visibility and user experience

Sunlight readable displays utilize advanced technology and materials to provide excellent visibility in high brightness and reflective environments. These displays show clear, crisp images and information in sunlight, making it easy for users to access the data and information they need. When using such displays, there is no longer a need to laboriously adjust the viewing angle or use shadows to read the screen, improving productivity and the user experience.

Enhanced Safety and Reliability

For industries that work in outdoor environments, it is often necessary to operate equipment in bright sunlight. In such environments, using sunlight readable outdoor displays ensures they always have a clear view of critical operating instructions, monitoring data, and safety warnings. The high brightness readable displays are designed with heat-resistant materials and dust- and water-resistant measures to ensure that the displays operate reliably for long periods in outdoor environments. This helps to reduce the risk of incorrect operation and accidents, improving safety and reliability in the workplace.

Enhance product brand image

In an age of advertisements and messages, you want to capture potential customers' attention through visual and digital signage. Sunlight readable displays provide sharp and clear advertising, ensuring your brand and product information is well represented outdoors. These displays can make your product or service stand out and impress your potential customers.
