“…It can be seen that the red, green, blue, and yellow colors of the RGBY film are legible. Also, the four colors make RGBY four color display possible, what is beneficial to multicolor display. , Analysis above sufficiently proves that the RGBY film has four typical color states. The unique optical properties of RGBY film are attribute to the compositing of FeHCF and MoOHCF, proving that this novel method for preparing multicolor electrochromic films is feasible.…”

Although multicolor electrochromic materials and devices have been studied by many researchers, there is still none an inorganic single-layer film that has red, blue, and green three typical color states, while red, green, and blue (RGB) are indispensably for multicolor display. Iron hexacyanoferrate (FeHCF) is a kind of well-studied inorganic electrochromic material with relatively colorful properties and a great family of analogues. In this Research Article, the RGBY film with red, green, blue and yellow four typical color states are obtained successfully by coelectrodeposition of FeHCF and molybdate hexacyanoferrate (MoOHCF). This film contains the electrochromic properties of both components. Moreover, benefiting from its high A+ (alkali cation ions that can insert/extract into/from the framework, such as Li+ and K+) content, the redox process of RGBY film can be fully completed to achieve rich color variation. The absorptivity adjustment range of RGBY film at 730 and 440 nm are 0.81 and 0.43, respectively. The response time of RGBY films varies from 3 to 30 s between states and maintains its optical properties without significant decay during 1000 cycles. Finally, a pixelated electrode and a facile electrochromic device based on RGBY film have been developed to exhibit its high application potential in nonemission display field.

“…Liquid crystal displays (LCDs) have slow responses as compared with cathode ray tube (CRT) displays because of LCD hold time [1][2][3], so ghost phenomenon or motion blurs are often perceived around fast moving objects in LCDs. To reduce the motion blurs, backlight flashing [4], signal overdrive [5], or frame rate up-conversion (FRUC) [6][7][8][9][10][11][12] can be used.…”

Robust Motion Compensated Frame Interpolation Using Weight-Overlapped Block Motion Compensation with Variable Block Sizes to Reduce LCD Motion Blurs

Liquid crystal displays (LCDs) have slow responses, so motion blurs are often perceived in fast moving scenes. To reduce this motion blur, we propose a novel method of robust motion compensated frame interpolation (MCFI) based on bidirectional motion estimation (BME) and weight-overlapped block motion compensation (WOBMC) with variable block sizes. In most MCFI methods, a static block size is used, so some block artefacts and motion blurs are observed. However, the proposed method adjusts motion block sizes and search ranges by comparing matching scores, so the precise motion vectors can be estimated in accordance with motions. In the MCFI, overlapping ranges for WOBMC are also determined by adjusted block sizes, so the accurate MCFI can be performed. In the experimental results, the proposed method strongly reduced motion blurs arisen from large motions, and yielded interpolated images with high visual performance and peak signal-to-noise ratio (PSNR).
