Abstract— A method of preparation of positive O films with the tilt angle of the optic axis continuously controlled in the range 0–90° is proposed. It is based on the use of reactive mesogens and alignment materials that provide a wide range of pretilt angles. The method developed allows for further improvement in the viewing‐angle characteristics of LCDs with O compensation films.  相似文献

镍铬薄膜电阻的制备热处理分析   总被引:1,自引:0,他引:1  
在采用磁控溅射方法制作用于集成电路的镍铬薄膜电阻过程中,发现在对薄膜热处理日寸薄膜的电阻特性发生了有规律的变化,这种变化不是单纯的线形增大或减小.针对这种现象,我们经过分析认为,由于金属薄膜的电阻率不同于块金属的电阻率,已不是定值,它与金属膜厚有着一定的关系,而热处理所产生的凝聚效应、氧化效应和稳态效应对不同厚度的薄膜电阻率的影响程度是不一样的,因此电阻经处理后的变化值最终表现出不同的变化趋势.这一现象的发现对我们今后在集成电路镍铬合金薄膜电阻的设计优化方面具有较高的参考意义.  相似文献

In this article, we present a new versatile method for calculating the interference colour of any configuration of thin, optically isotropic, dielectric films. This method is free from common weakness of previous methods, namely the poor accuracy for large angles of incidence of light. This method gives full control over the accuracy and speed of computations, and allows for adjustments of the parameters according to the physical and chemical properties of the film, in order to present the optimal results. We also present a formula to model the thickness of thin films made up of liquids, such as soap bubbles.  相似文献

With the emergence of new media, interactive film projects have mainly struggled to resolve the contradiction between dramatic structures and interaction. Dramatic film presents identification with the main character, where the viewer is constantly oppressed by the narrative, and therefore lost in illusion. In this context, when we bring on the scene interaction, the drama apparently starts to lose its power.

In this article, a new interactive film model based on Brechtian film theory is proposed. This model presents a new way of spatiotemporal construction where different audiovisual combinations can be viewed successively, and this way the viewer can actively construct his/her own story. Theoretical framework of the Brechtian interactive film model is supported by an interactive film application, named Academia. The main feature of the model is that, while interaction is very simple, the continuity of the narrative is preserved and the film requiring an intellectual level of interpretation.  相似文献
