Types of OLED Screen
The versatile OLED screen comes in various types to cater to different preferences and needs.
- White OLED (WOLED): This type of OLED utilizes a white light source combined with color filters. Although WOLED displays offer reasonably good brightness levels, the use of color filters may lessen the light's overall efficiency. Consequently, these screens are less energy efficient when compared to other OLED technologies. Nonetheless, WOLED panels are recognized for their accurate color reproduction and excellent visibility. They are often employed in television sets and computer monitors.
- Phosphorescent OLED (PHOLED): In PHOLED screens, materials called phosphors are used to emit light. This method is more energy-efficient than WOLED because it can produce pure red, green, and blue light without color filters. As a result, PHOLED displays tend to have better brightness and longer battery life, making them a good choice for smartphones and other portable devices.
- RGB OLED: An RGB OLED screen has individual red, green, and blue organic light-emitting diodes (OLEDs) for each pixel. Like WOLEDs, RGB OLEDs can provide bright colors and good contrast, but they usually consume more power. In addition, the RGB arrangement may cause color fringes or bleeding issues on lower-quality screens. Nonetheless, high-end smartphones and wearable gadgets often utilize RGB OLED displays for their vivid color possibilities and deep blacks.
Function and features of oled screen
Supplier and buyer of screen-related commodities may find opportunities by studying the functions and features of an OLED screen.
- Display technology: By utilizing organic electroluminescence, OLED screens deliver amazing imagery. Each pixel can emit light on its own, adjusting its brightness and color for enhanced visibility, particularly in low-light locations.
- Better contrast: Because OLED screens can turn off individual pixels, the black levels and contrast ratios are exceptional. HDR material may be considerably more beautiful because of this. Improved picture quality is a result of the greater contrast ratios made feasible by OLED.
- Thin and flexible: Because OLED screens don't need a backlight or constrained lighting sources, they may be produced thinner and lighter. This accommodates thinner and lighter goods. Additionally, flexible and curved displays may be made because of this screen's flexibility, which opens up new goods and applications.
- Power-efficient: When displaying darker pictures, OLED screens save more energy because there isn't a backlight. This lowers energy consumption and prolongs battery life on portable gadgets.
- Faster response time: Because OLED screens have a quicker response time, motion blur is reduced, and gaming performance is enhanced. High-refresh-rate displays work well with this.
- Wide viewing angle: Because of its superior angle visibility and color fidelity, an OLED display provides a more enjoyable viewing experience. It is unnecessary to adjust the screen alignment to view the contents magnificently.
- Durability and life span: In mobile devices, OLED displays provide great durability and performance, although if, over time, the organic materials degrade and cause screen burn, this poses a concern. Users can take essential precautions to avoid screen burn and extend the life of their display with intelligent management and screen care.
Scenarios
Due to its superior picture quality, color accuracy, and contrast, OLED technology is taking over the display market. The global organic light-emitting diode (OLED) market reached a value of about $34 billion in 2021 and is projected to grow between $70-$85 billion by 2030. By 2025, the global market for LCDs is forecasted to reach $77 billion.
An OLED screen has multiple usage scenarios due to its better contrast, sharper image, and brighter display. Here are a few highlighted below:

TV manufacturers are using this technology to create vibrant and high-resolution color images for their target consumers.
- Smartphones: An increase in smartphone usage has impacted the global OLED market significantly over the years. The kind of OLED screen a smartphone has can make or break a sale. Players in the OLED market for mobile phones are strategically partnering and contracting with key smartphone companies such as Apple, Samsung, and Sony to expand their market share.
- Tablets: Like smartphones, tablets with OLED screens are in demand. An increase in tablet usage has positively impacted the growth of the OLED market. Game and graphic designers tend to gravitate towards tablets with OLED screens due to their vibrant colors and better contrast ratios.
- Wearable devices: Devices such as smartwatches with an OLED screen save battery life. Wearables with OLED screens deliver better visibility in various ambient light surroundings. The wearable market is projected to grow exponentially in the next few years.
- Lighting: OLED lighting is unique and different from traditional lighting. Different lighting applications are using OLED lighting to enhance aesthetic value and reduce energy consumption. OLED lighgting s beneficial for architectural, automotive, and industrial applications.
How to choose Oled Screen
Choosing the right OLED screen requires careful thought and awareness of the specific needs of the target audience. To pick the ideal display for wholesale purchasing, consider the following factors:
- Screen Size and Resolution: Various screen sizes are available for various applications; hence, the desired screen size should be determined first. The most recent OLED technologies ensure excellent picture quality after establishing a target screen size. The choices of end customers should be taken into account while selecting screen size and resolution.
- Types: Find out about the different OLED screen types available. The flexible OLED screens' bendability makes them suitable for unusual display designs. The digital signage possibilities provided by the Transparent OLED displays are excellent for branding and imaginative projects.
- Brightness and Environmental Suitability: Brightness range must be suitable for indoor applications or low-light situations depending on the target environment. Consider the screen's visibility under its intended lighting conditions while tackling outdoor displays or bright spaces, and choose a model with higher luminosity.
- Connectivity and Integration: Ensure compatibility with the devices and systems by assessing the OLED display screen's connectivity options, such as ports and protocols. Choose screens that have the necessary connections to incorporate easily into the intended application, whether considering HDMI for multimedia devices or USB for content upload.
- Durability and Reliability: Select screens that provide consistent operation and long lifespan after considering the anticipated usage and operating circumstances. Think about aspects like viewing angle stability, color accuracy, and pixel retention solutions. Screens with good reliability lower replacement costs and maintenance needs, ensuring long-term user satisfaction.
- Vendor Support and Updates: Choose a trusted supplier that offers prompt support, OLED screen upgrades, and a thorough understanding of display technologies. To eliminate potential difficulties, examine the supplier's reputation and procedure for testing and certifying products. Ensure the supplier has experience in providing displays for the targeted applications and industries.
- Cost and Value: Evaluate the cost of various OLED screens in relation to their features, performance, and longevity. Consider the total cost of ownership, including potential replacement costs, when determining value. Select screens that offer a favorable balance of cost and value for the intended application.
Q & A
Q: Does OLED use a backlight?
A: No, the OLED screen does not use a backlight. The individual organic LEDs produce their own light, so no backlight is required. This fundamental difference gives OLED screens superior contrast since there is perfect black level control.
Q: How does an OLED display work?
A: An OLED screen works by passing an electric current through organic compounds that emit light when excited. Each pixel can be turned on or off separately, giving excellent image quality and extremely thin display technologies.
Q: How long does an OLED screen last?
A: The lifespan varies depending on usage and conditions, but generally, OLED screens can last up to 100,000 hours or more before significant degradation occurs. Factors like brightness levels and temperature also affect longevity.
Q: What is bad for an OLED screen?
A: Prolonged static images at high brightness can cause permanent damage or burn-in effects over time. Screen savers and low-intensity levels help minimize risks. Very high temperatures also negatively impact OLED screens' longevity.
