In this study, the compensation effect of a 7.56‐inch MicroLED product with pure PAM driving scheme is verified using conventional optical (Demura) method. A theoretical analysis overcompensation problem due to variation color coordinates devices luminance performed. The related phenomenon generates an about 10 gray levels at specific level and luminance.
As a widely acknowledged next‐generation display technology in the industry, Micro LED has its advantages, but also faces significant issues with mura phenomenon. Moreover, traditional Demura algorithms have numerous limitations when applied to LEDs, leading limited compensation effects. This paper first introduces specific problems of current applications and proposes algorithm based on Generative Adversarial Networks (GANs) from deep learning, targeted address these issues. Subsequently,...
Influences of anti‐reflection (AR) and anti‐glare (AG) components on display performance were studied, especially for the scenario indoor text reading. Both ambient influence clarity analyzed in search a cost‐effective combination two components. A design method based human eye sensitivity curves was developed optimization AG component.
Optical compensation (Demura) is a crucial technology in the production process of active‐matrix organic light‐emitting diode (AMOLED). And with continuous advancement micro (Micro LED) technology, Demura techniques are also employed to enhance quality Micro LED products. This article initially applies an AMOLED full grayscale scheme perform on 9.38‐inch sample. However, effect falls short expectations. Subsequently, analysis and for display effects each level conducted, highlighting...
We proposed a novel method for evaluating short range uniformity. It was used to compare the performance of micro‐LED display which driven by PAM and PAM+PWM hybrid respectively. The results showed that driving had significant advantages, corresponded subjective visual feeling.
Micro‐LED is a new display technology that offers advantages such as high brightness, contrast, and low power consumption. However, the performance of greatly affected by temperature, leading to color shift easily. To address this issue, paper proposes machine learning‐based approach for achieving global compensation, which exhibits including compensation accuracy, good smoothness, strong generalization performance. Experimental validation using both measured simulated data demonstrates...

In this study, a loop iterative approach is employed to gradually get closer the actual red, green, and blue color coordinates brightness ratio under given grayscale realize chromaticity compensation (Color Demura) for LTPS TFT MicroLED display. This applied 9.38‐inch 480 × 960 resolution display, achieving uniformity more than 95% non‐uniformity less 1JNCD, respectively.
With the continuous development of in‐car display applications, demand for glasses‐free 3D screens is gradually increasing. This article adopts a high‐resolution 4K screen based on prism technology， and equipped with human eye tracking system implemented using regular monocular camera. configuration enables instrument to provide high‐quality effect within large visual range, addressing limited viewing area issue associated traditional displays. Due constraints in camera hardware conditions,...

In this paper, a method of reducing the influence IR‐drop in OLED display for color gamut mapping (CGM) is described. Due to IR‐drop, parameters can be hardly calculated only by formulas, which make inaccuracy CGM. This algorithm uses data specific gray scale find out rule arbitrary scale. The easy and accurate reduce making CGM better applied displays.
As we know, OLED has a short lifetime compared with LCD, due to its material characteristic[1], which leads fact that improved performance of in display , especially vehicle products is one the most important factors market development OLED. In this paper, novel algorithm for luminance attenuation was proposed, using method statistical regularity.
