The conventional virtual viewpoint generation methods use the pixel filling algorithm to fill the image holes and restore artifacts on the generated virtual viewpoint images. However, the repaired virtual viewpoint images cannot meet the requirements of the autostereoscopic display. In order to obtain virtual viewpoint images with high quality, we propose a virtual viewpoint image generation method for autostereoscopic display based on deep convolutional neural network (DCNN). The method uses a randomly ini 关键词：autostereoscopic display;virtual viewpoint image;deep convolutional neural network;image inpainting- 359

In this paper, the typical hydrogen bond-assembled supramolecular liquid crystal materials are summarized over the past decade. Their preparation methods and molecular structures are presented, and their photoelectric properties and self-assembly characteristics are compared, as well as their applications in optoelectronic devices are prospected. According to the kinds of hydrogen bonds and the molecular structures, these materials are mainly divided into two categories:closed-type and open-type structures. 关键词：hydrogen bond;self-assembled;supramolecule;liquid crystal;complex- 373

However, neither reactive ion etching (RIE) nor enhanced capacitive couple plasma (ECCP) could well etch this film. Accordingly, the combination of RIE and ECCP was proposed to improve the etching effects. When the thickness of planarization layer was 2.0μm, we first etched 1.5 μm of the planarization layer by RIE mode (7 kW/20 Pa), then etched the rest as well as the underneath silicon nitride film by ECCP mode (5 kW+4 kW/8 Pa); the surface of via hole was smooth without undercut issue, and the via hole critical dimension (CD) was 6.12 μm. These results lay a solid foundation for the design and fabrication of the high-resolution and low-power products with this new planarization layers.关键词：TFT;planarization layer;low-dielectric constant;dry etching

Achromatic polarization rotator is a kind of optical element which can rotate the polarization angle of incident polarized light, its optimized aim is the same rotational angle for the polarized light through the rotator in wider wavelength range. In this paper, we present two kinds of achromatic polarization rotators. One is composed of six wave plates. The other is composed of four wave plates. TechWiz LCD 1D software is used for simulation. The transmittance of the polarization rotator composed of four w 关键词：achromatic;transmittance;polarization rotation;linearly polarized lights;wave plates- 354

This paper analyzes the vital factors of affecting black uniformity from product design, process parameters and process control, and finds that it is affected by the black pattern brightness and Liquid Crystal Display Module flatness. The lower brightness of the black pattern, the better black uniformity will be. The better LCM fatness is, the better black uniformity will be. Combining with the production of TFT-LCD, a black uniformity control scheme is proved effectively, through reducing the brightness of black pattern and improving LCM flatness.关键词：thin film transistor liquid crystal display;black uniformity;brightness of the black pattern;flatness;back light unit

In TFT-LCD industry, in the rubbing process, some defect like rubbing Mura, L0 block, rubbing scratch are easy to happen. Investigation and experiment found that the rubbing Mura is associated with weak Rubbing strength and weak coordination force of polyimide film, which results in pixel light leakage. Choosing the nylon cloth with good rubbing strength, and controling cloth life under 100 sheets, can effectively control the occurrence of rubbing Mura. Improving rubbing strength through craft adjustment, Z 关键词：rubbing process;rubbing Mura;L0 block;scratch- 369

To overcome the problem that images captured by the current imaging system with the multi-primary-color image sensor cannot be transmitted under the three-primary-color channel, as well as the wide color gamut display system using multi-primary color filters or backlight does not have multi-primary-color image contents, this paper presents a method transmitting four-primary- color images only with the data amount of the YUV format. The quadrilateral constituted by four-primary colors is decomposed into two 关键词：wide color gamut;four-primary-color;YUV;color transform;codec- 338

In order to solve the problems of traditional color image denoising algorithm, such as detail blur, false color and poor denoising effect, a sparse representation color image denoising algorithm based on intrinsic decomposition is proposed. By utilizing the intrinsic image decomposition advantages of good color retention and detail recovery, the noisy color image is decomposed into reflectance and shading which reflect the true color feature of the image and the image brightness feature, respectively.

The reduced dimensional factorized convolution method and the compact generative model (RFCG) are proposed in order to solve the computational complexity and over-fitting problems in the continuous convolution operators for visual tracking(C-COT). Some feature channels in the C-COT are selected in advance, then the convolution operator is factorized, and the reduced dimension matrix and filter are obtained by combining Gauss-Newton method and conjugate gradient iteration (CG), so as to reduce the computatio 关键词：C-COT;factorized convolution;over-fitting;compact generative model- 337
