NetBeans平台软件开发单元测试技术的研究

软件开发和软件测试就像两兄弟,他们密不可分、协同合作,目标只有一个,那就是成功开发出高质量的软件。开发与测试之间的关系如此密切,让我们很难彻底的将两者严格的划分开来。单元测试做为测试的一部分,一般都由编码人员来承担,对于模块级一直都是谁编码、谁测试。因此测试不仅仅是测试人员的事情,作为编码人员也需要懂得测试的基本方法,以通过单元测试提交高质量的程序模块。

Analysis of image sticking on a real MVA Cell

Abstract— Image‐sticking phenomenon is one of the most important issues affecting LCDs, especially LCD TV. It is known that image sticking is caused by residual DC voltage. An analysis of the cause that induces image sticking on a real LCD cell is very difficult to perform and is rarely reported. In this paper, the impurities that cause boundary image sticking on a real MVA cell was analyzed by examining a cross section of a cell, the bulk LC layer, the vicinity of the LC layer, the LC layer/PI alignment film interface using microanalysis methods such as infrared micro‐spectroscopy (μ‐IR) and micro‐sampling mass spectrometry (μ‐MS). It is clarified that there is quite a bit of aromatic acid at the boundary of the image‐sticking area than in the normal area at the LC/PI alignment film interface on the color‐filter side, not the TFT side, and it is assumed that aromatic carboxylic acid, a negative charged material, is condensed at the LC/PI alignment film interface on the color filter side by an electrically driven DC component inducing an electric‐condenser residual DC voltage.     

Diffractive backlight grating array for mobile displays

Abstract— The display backlight unit (BLU) is the most power‐consuming subunit in mobile liquid‐crystal displays. The state‐of‐the‐art BLUs utilize scattering, refractive, and reflective microstructures to generate a uniform distribution of white light through the display. More effective means of transmitting light through the display color filters could be obtained by using diffraction, but previously proposed diffractive backlights do not fully utilize all the possibilities to design gratings effectively for optimal color separation and outcoupling. This paper presents a new pixelated diffractive backlight grating array as an approach for overcoming these obstacles in BLU design. A model array was fabricated to couple out red, green, and blue primary colors from the respective subpixel locations. The results show that it is possible to manufacture such an array and that the light couples out as intended, giving a starting point to design mobile‐display modules with low light‐transmission losses.
