Disclosed is a liquid crystal display device capable of preventing a grounding clip, which is combined to an end of a mold frame to ground a printed circuit board to a top chassis, from making electrical contact with a display unit.

本发明公开了一种能够防止接地支架与显示单元电接触的液晶显示器，其中接地支架结合到模框的一端以将印刷电路板接地到顶部机壳上。

Also, by using a novel offset architecture, as opposed to completely overlapped architecture, for the differential transmission pair, a 33% reduction of thickness is achieved in the design of a miniaturized common-mode filter with multi-layer LTCC technology. In view of increasing need of high-speed clock and data circuits to control their skew problems, a design of LTCC delay line is then conducted. To improve the waveform distortion associated with the microstrip/stripline-type meander delay line, a miniaturized high-frequency 3-D delay line with grounded guard traces is introduced. By means of 3-D structure, the 233 ps delay time, which requires extra board space amounting to a factor of 2.34 by stripline type meander delay line, can be shrunk into an EIA 1206 form factor.

为因应高速时脉及高速线路的不断发展，用於控制讯号、时脉同步的延迟线路需求日益增加，接著讨论的题目便是应用低温共烧陶瓷制程技术设计多层的延迟线路元件，为了改善在微带线/带线型折线式延迟线路波形失真的问题，论文中提出以接地的防护线来设计小型化的三维多层延迟线路元件，比较应用带线型折线式延迟线路和应用三维架构设计的延迟线路元件，同样提供233 ps的延迟时间，多层架构设计之延迟线路可缩小至EIA 1206 的尺寸，省下2.34倍的电路板面积。
