Earlier this year we reported that Apple has decided to sign up BOE as its AMOLED supplier for the upcoming budget iPhone SE4 (with a 6.1" AMOLED display). According to reports back then, Apple's low price target ($25) was not profitable for Samsung that decided to not supply any AMOLEDs for this iPhone model. According to new reports from Korea, Apple now signed up LG Display to supply some of its iPhone SE4 panels - mostly backup (BOE had its issues with Apple before) and support, as BOE will remain the main panels supplier.

OLED emitter materials are the heart of the OLED device, and the materials that make the most impact on the performance of the OLED display. Most OLED displays utilize red, green and blue emitters. The efficiency of the current state-of-the-art commercial red and green OLED emitters is excellent - it is in fact close to 100% internal quantum efficiency (IQE) which means that you cannot improve much on the efficiency of the emitter itself (there's still work to be done on getting the light out of the device). Blue OLED emission is a completely different story - current commercial blue emitters suffer from very low efficiency, around 25%. This means that three quarters of the energy goes to waste. Changing to a 100% IQE blue emitter could end up improving the total display efficiency by 20-30%.

Visionox announced that together with Sheng Microelectronics and Sage Microelectronics it has developed the world's firs AMOLED device driver that is powered by RRAM memory. All AMOLED drivers on the market use a combination of SRAM memory, OTP (one-time programmable memory) and external Flash memory (for non-volatile memory), mostly to perform the Demura compensation function. The RRAM memory enables lower cost of production, higher efficiency - and smaller area.

Specific calibration standards are recommended for different types of professional displays, such as OLED or LED. For OLED displays, standards like the Rec. 709 or DCI-P3 are commonly used to achieve accurate color reproduction. LED displays may require different standards based on their specific technology and capabilities to ensure optimal color accuracy.
Professional displays should be calibrated using calibration standards regularly to maintain optimal performance. The frequency of calibration depends on factors such as the display type, usage patterns, and environmental conditions. In general, it is recommended to calibrate professional displays at least once a month to ensure consistent color accuracy.
Calibration standards can help in achieving specific color spaces like sRGB or Adobe RGB on professional displays by providing precise instructions for adjusting color settings. By following these standards, professionals can calibrate their displays to accurately reproduce colors within the desired color space, ensuring that their work is displayed as intended across different devices and platforms.
Industry guidelines and recommendations for using calibration standards in professional display calibration emphasize the importance of accuracy, consistency, and reliability in color reproduction. Professionals are encouraged to follow established standards like ICC profiles, DCI standards, and SMPTE standards to ensure that their displays meet industry requirements and deliver high-quality visual experiences to their audience.
When selecting calibration standards for professional displays in a professional setting, key factors to consider include the display type, color space requirements, industry standards, and workflow needs. It is important to choose calibration standards that are compatible with the specific display technology and can help achieve the desired color accuracy and consistency for the intended use of the display. Additionally, considering the long-term maintenance and support of the calibration standards is essential to ensure continued optimal performance of professional displays.
When selecting calibration software for an LED display, it is important to consider factors such as color accuracy, brightness levels, contrast ratios, and gamma settings. Look for software that offers advanced features like white balance adjustment, color temperature control, and uniformity correction. Additionally, ensure that the software is compatible with your specific display model and supports the necessary connection interfaces. It is also beneficial to choose software that provides real-time monitoring and reporting capabilities for efficient calibration processes. Consider options that offer automatic calibration routines, customizable profiles, and support for different color spaces to achieve optimal display performance. Conduct thorough research and read reviews to find a reliable and user-friendly calibration software that meets your specific requirements.
When calibrating LED walls in retail spaces, several considerations must be taken into account to ensure optimal performance. Factors such as ambient lighting conditions, viewing angles, color accuracy, and pixel pitch all play a crucial role in achieving the desired visual impact. It is important to calibrate the LED walls to match the overall aesthetic of the retail environment and to accurately represent the products or branding being displayed. Additionally, regular maintenance and adjustments may be necessary to address any issues that arise over time, such as color consistency or brightness uniformity. By carefully calibrating LED walls in retail spaces, businesses can create a visually engaging and cohesive experience for customers, ultimately enhancing the overall shopping experience.
Software plays a crucial role in the LED video wall calibration process by providing advanced tools and algorithms for adjusting the display settings to achieve optimal performance. Calibration software allows users to fine-tune parameters such as brightness, contrast, color balance, and gamma correction to ensure accurate color reproduction and uniformity across the entire video wall. Additionally, software can facilitate the alignment of individual LED modules, pixel mapping, and geometric correction to eliminate any visual discrepancies or distortions. By leveraging sophisticated software solutions, technicians can streamline the calibration process, save time, and achieve superior image quality on LED video walls for various applications such as advertising, entertainment, and digital signage.
To calibrate a multi-panel LED video wall setup, one must first ensure that all panels are properly connected and powered on. Next, use a calibration tool or software to adjust settings such as brightness, contrast, color temperature, and gamma levels. It is important to also check for any inconsistencies in color or brightness across panels and make necessary adjustments to achieve a uniform display. Additionally, fine-tune settings such as color balance, saturation, and sharpness to optimize the overall visual quality of the video wall. Regularly monitor and recalibrate the setup to maintain optimal performance and ensure a seamless viewing experience for users.
Static calibration involves calibrating a device or instrument using fixed reference points or standards without any movement or change in conditions. This type of calibration is typically done in a controlled environment to ensure accuracy and precision. On the other hand, dynamic calibration involves calibrating a device or instrument while it is in motion or experiencing changing conditions. This type of calibration is often used for equipment that operates in real-world scenarios where conditions are not constant. Dynamic calibration requires specialized techniques and equipment to account for variables such as vibration, temperature fluctuations, and other environmental factors. Both static and dynamic calibration are essential for ensuring the reliability and accuracy of measurement instruments in various industries such as manufacturing, aerospace, and automotive.
To maintain calibration accuracy over time, it is crucial to regularly perform recalibration procedures, adhere to manufacturer's guidelines for maintenance, and monitor environmental conditions that may affect the accuracy of the calibration. This includes ensuring proper storage of calibration equipment, conducting routine inspections for wear and tear, and implementing a robust quality control program to detect any deviations in calibration accuracy. Additionally, utilizing advanced calibration software, conducting regular proficiency testing, and engaging in continuous training and education on calibration best practices can help to sustain accuracy levels over time. By implementing a comprehensive calibration management system and staying up-to-date on industry standards and advancements, organizations can effectively preserve calibration accuracy for the long term.
