Abstract ：
Inadequate exposure of imaging devices in low-light environments results in a loss of image information, significantly deteriorating the image quality. However, current low-light image enhancement algorithms commonly suffer from issues such as color distortion and loss of fine details and textures. In this paper, we propose a frequency-guided dual-collapse Transformer (FDCFormer) network. First, in response to color distortion after enhancement, we propose a dual-collapse Transformer that effectively aggregates features from both spatial and channel dimensions, thus capturing global information. Subsequently, because relying solely on enhancement in the spatial domain often makes it difficult to preserve fine details and textures, we design multiple mixed residual fast Fourier transform blocks as additional frequency information guidance branches, focusing on local detail information at the image edges. Additionally, we employ an adaptive dual-domain information fusion module that combines spatial domain and frequency domain information to enrich the final output features. Extensive experiments on multiple publicly available datasets demonstrate that our FDCFormer outperforms state-of-the-art methods, exceeding Retinexformer by up to 0.93 dB on average across five paired datasets. We also employ our method as a preprocessing step in dark detection, our method improves mean average precision (mAP) by 1.9% over the baseline model on ExDark dataset, revealing the latent practical values of our method. The corresponding codes will be available at https://github.com/Fly175/FDCFormer.

Abstract ：
Due to the simple structure, single-contact light-emitting diode (SC-LED) holds promise for applications in ultrahigh resolution micro-displays. However, the required alternating current (ac) operation poses challenges for grayscale modulation in image display applications. Therefore, it is of great significance to develop a potential grayscale control technology for the ac-driven SC-LEDs. In this work, the optical and electrical characteristics of the SC-LEDs are investigated, and an anomalous pulsewidth modulation (A-PWM) technology is proposed. In the A-PWM mode, the brightness decreases with the increasing pulsewidth, which is totally different from conventional pulsewidth modulation. The carrier transport model and the circuit model are established to clarify the A-PWM mechanism. Furthermore, the brightness division is carried out on the basis of the A-PWM, and the human eye brightness perception model is established. Nonlinear correction is applied to align the brightness change with the characteristics of human eye perception. This work proposes a brightness modulation method suitable for SC-LEDs, which is expected to be applied to ac-driven nano-pixel light-emitting displays.

Abstract ：
The charge capture of color inks in chromatic electrowetting electronic paper, the contact angle hysteresis and inconsistent aperture ratio result in a narrower color gamut and reduced contrast of the display screen. To address the issue, we propose an algorithm of the adaptive color conversion and the dynamic enhancement display based on the aperture ratio of the chromatic electrowetting. Firstly, the relationship between the aperture ratio of electrowetting and the increase or decrease of voltage was tested through an experimental platform. Then, combined with the change of the aperture ratio, the reasonable grayscale allocation is made for color space conversion. Furthermore, considering the average grayscales of each color, we design a method of the dynamic contrast enhancement and histogram equalization based on the segmentation of aperture ratios. In addition, in view of the problem of grayscale loss in the reflective display, we propose an adaptive algorithm of domain error diffusion with saturation enhancement to compensate for color loss. The experiments demonstrate that the images processed by our algorithm have shown certain improvements in evaluation indicators compared to images processed by other methods. Most significant of all, it has better visual display effect on chromatic electrowetting electronic paper, displaying more details.

Abstract ：
In order to solve the problem that the color of the reflective display color electrowetting display is inconsistent under ambient light with different color temperatures, which affects the color reproduction of the displayed picture, a color correction method based on the spectral reflectance characteristics of color electrowetting display is proposed. The spectral correspondence of the display color under ambient light with different color temperatures is obtained through the spectral reflectance characteristics of color electrowetting display, so as to establish the mapping relationship of the display color of color electrowetting display under ambient light with different color temperatures. According to the mapping relationship, the input color data is corrected to reduce the color difference of the displayed colors under ambient light with different color temperatures. The experimental results show that the chromaticity data of 100 test color blocks before and after the correction by the method in the two experimental light sources are reduced by 55% and 35% respectively with the average color difference of the standard light source, and the average subjective evaluation Z-scores of the corrected display images are 0.45 and 0. 25.
