Line image sticking is one of issue all along which needs to be improved in TFT-LCD industry. In order to solve this problem, the evaluation of line image sticking level and the common voltage(Vcom) distortion of different productions were tested, and the effect of Vcom distortion on line image sticking was investigate in the aspect of array mask design. First of all, laser wedding was used to help us to test the signal of Vcom in panel, then the Vcom distortion could be tested when data voltage was inputte 关键词：line image sticking;distortion of common voltage;array mask design- 361

Polymer Dispersed Liquid Crystal (PDLC) is a high performance electro-optic material. The electro-optical properties of PDLC have great influence on the performance of applications based on PDLC. In this paper, we studied the effect of UV intensities on electro-optic properties of PDLC. PDLC samples are fabricated by polymer induced phase separation (PIPS) method initiated by UV irradiation. Four PDLC samples were prepared using four UV light intensities of 1 mW/cm2, 1.8 mW/cm2, 3 mW/cm2 and 9 mW/cm2.

A novel low bandgap donor-acceptor conjugated polymer (PBDID-TCNT) was prepared by Stille cross-coupling reaction to explore the relationship between polymer structure and performance and obtain electron transport type semiconductor material. The thermal, optical, electrochemical properties, and microstructures were investigated using thermogravimetric (TG), different scanning calorimetry (DSC), ultraviolet-visible-near infrared spectrometer (UV-Vis-NIR), cyclic voltammetry (CV)and atomic force microscope ( 关键词：conjugated polymer;electron transport;organic thin-film transistor- 317

Based on the density functional theory, ten kinds of fluoro-substituted liquid crystal derivative molecules, 4-butyl-4'-[(4-butylphenyl)acetylene]biphenyl, are simulated using Gaussian09 package with Opt+Freq optimization type and B3LYP/6-311g basis set. Comparing the substituted position and number of fluorine atoms, the absorption in terahertz region is discussed. The results show that the position and number of fluorine atoms can significantly influence the absorption peak and intensity of the functional 关键词：fluorine liquid crystal;terahertz;absorption;spectrum;Gaussian simulation- 310

In the TFT lithography process, the segment difference of the photoresist make the lithography level of the each region of the photoresist be different on the same lithography plane, which seriously affect the quality of the lithography pattern. In this paper, the reason for the effect of the segment difference of photoresist on the lithography pattern is analyzed. Based on the characteristics of the light intensity change near the focal point of the lithography system of the projection lithography machine 关键词：segment difference;photoresist;lithography;lithography plane;light intensity- 339

In order to solve the problem of current focus measure function, such as low sensitivity, poor robustness and easy to enter the saturated zone, a new function based on gray gradient and dark channel is proposed. Firstly, a characteristic is analyzed and proved that a clear image has brighter and sparser dark channel compared with a defocus image. Secondly, the L0norm of dark channel is selected to estimate the degree of defocus. Finally, a new focus measure function is constructed by integrating the gray gr 关键词：auto-focusing;focus measure function;dark channel;definition evaluation- 305

Owing to the existence of atmosphere, the transmission of the light waves will be interfered by the atmospheric turbulence. It will make the image blurred, the pixels got deviated and the image signal to noise ratio decreased. Therefore, the research of degraded image restoration technology has become an important way to obtain high performance image in space optical imaging system. In this paper, the research progress of degraded image restoration technology is systematically combed and analyzed.

This paper presents an elimination image ORB mis-matching method based on Mask R-CNN in order to improve the accuracy of multi-target image matching ORB. First of all, the algorithm identifies the image by faster R-CNN method, and it uses Region Proposal Network to obtain the interest area and category labels which are marked by rectangular box. We can get the forecast category and coordinate information of the interest area by this step. And then we correct the pixel level by the convolution layer of the F 关键词：ORB matching;Mask R-CNN algorithm;Mis-matching- 320

发布时间：2020-07-06 - 摘要：For the problems of the autostereoscopic 3D display, such as the fixed and unadjustable optimal viewing distance, this paper proposes a variable-viewpoint stereo image synthesis algorithm based on the platform of Unity3D using Cg language programming. The algorithm adjusts the pixel corresponding to the pitch of lenticular lens based on the relationship between the optimal viewing distance and the number of viewpoints, which can flexibly change the optimal viewing distance of the autostereoscopic 3D display by changing the number of viewpoints flexibly. The experimental results show that the stereo image synthesized by this algorithm can adjust the optimal viewing distance, and the error between the number of viewpoints measured and the number of viewpoints calculated is not obvious. The image crosstalk is low and the synthesis efficiency is high, and it satisfies viewers to watch stereo images comfortably in different distances.关键词：autostereoscopic 3D display;viewpoint;Unity3D;image synthesis
