In this paper, Zinc oxide (ZnO) inorganic films as an alternative alignment layer for liquid crystal displays were deposited at fixed oblique angles on Indium Tin Oxide (ITO) glass using magnetron sputtering. By controlling the wettability of the ZnO film through annealing, the alignment states of Liquid crystal molecules can be manipulated. The results showed that the transmittance of the specially treated ZnO film substrate met the need of LCD panels in the visible light band. The LCD cells fabricated using ZnO-based substrates have the similar transmittance-voltage curves as the one with electronically controlled birefringent (ECB) mode based on mechanically rubbed polyimide, and that the ZnO-based LCD cell has a lower threshold voltage due to the slightly higher pretilt angle of the liquid crystal molecules. In addition, the ZnO-based liquid crystal cell has a nearly half faster response time than the PIbased cell.","PeriodicalId":254992,"journal":{"name":"2022 5th International Conference on Circuits, Systems and Simulation (ICCSS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123033571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SEB triggering mechanisms contain the amplification bipolar effect and following impact ionization in the high field region. By comparing the simulation results from conventional LDMOS and proposed NDP LDMOS, the carriers induced by heavy ion can be quickly absorbed to drain and source electrode through NDP layer, so that the proposed NDP LDMOS can achieve better SEB performance than conventional one.

Gestures can bring more natural, comfortable, and effective communication between people and machines. However, in some complex scenarios, such as rooms with looming lighting, the robustness and universality of hand gesture recognition based on traditional cameras are insufficient, and the supporting algorithms tend to underperform in real-time, especially for embedded devices. This article explores methods of implementing gesture recognition based on Dynamic Vision Sensor (DVS). We obtained frame data by event-based accumulation and time-based accumulation. Then we apply preprocessing techniques such as sub-time window and overlapping frame to achieve higher accuracy on hand gesture recognition with the DVS. In this paper, we built a DVS-based gesture recognition system with the advantages of efficient data preprocessing, low memory cost, low latency, and competitive recognition ability in interaction scenarios. The recognition accuracy reaches 94.6%.","PeriodicalId":254992,"journal":{"name":"2022 5th International Conference on Circuits, Systems and Simulation (ICCSS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124764474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Charge collection is used to reveal the response mechanism of SET. By comparing the simulation results from the conventional LDMOS and proposed hardened NiN-LDMOS, the NiN-LDMOS has a lower charge collection of the drain electrode and shorter transient response time. A corresponding comparison was also made according to the different positions of BOX. Results show that with a heavy ion having the linear energy transfer (LET) value of 0.8pC/μm striking vertically into 60μm, the pulse width of the SET signal can be reduced from 24ns of the conventional LDMOS to 4ns of the NiN-LDMOS.

In lightweight convolutional neural networks, the depthwise separable convolution (DSC) is becoming the mainstream method. But in DSC, the pointwise convolution (PWC) with $1times 1$ filters still has abundant parameters and computation. In this paper, an more efficient convolution algorithm is proposed to replace PWC, named kernel shared group convolution (KSGC). KSGC is used to combine channel information, which can be seen as the same convolution kernel sliding on the channel. In addition, Winograd algorithm is used to mitigate the number of multiplications required by KSGC in this paper. A CNN accelerator using a novel processing element (PE) performs 1-D Winograd in KSGC was implemented on a Ultra96-V2 field-programmable gate array (FPGA).At 200MHz clock frequency, the accelerator achieved computational performance of 52. 7GOPS and performance-power ratio of 10.42GOPS/W.","PeriodicalId":254992,"journal":{"name":"2022 5th International Conference on Circuits, Systems and Simulation (ICCSS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133388066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, Carbon Nanodots (CNDs) have drawn great attention to be playing an essential role in the active layer of the PD. However, CND based solar-blind UV PDs, independent from sophisticated manufacturing method and extreme process conditions, has yet to be well developed. Herein, for the very first time, a vertical structured CNDs/graphene heterojunction type solar-blind UV PD is introduced, in which the CNDs is used as the photosensitive layer and the graphene is used as the transparent electrode, implemented with a low-cost and low-complexity fabrication strategy of CNDs. The device exhibits extraordinary responsivity of19.11 mA/W, normalized detectivity of $4.60times 10^{10}$ Jones and on/off ratio of 342 at low bias voltage of -5V under the illumination of1.5 mW/cm2 by 254 nm wavelength.
