简介:摘要:直到今天为盲人群体的生存状况是我国政府和社会长期关注的课题。我国目前有上千万盲人,是残疾人中不可忽视的一大群体。五感中的触觉对盲人产品感性设计起着至关重要的作用,因此智能手套要挖掘盲人的特殊心理需求,将视障人群的意志带入到设计的全过程,通过确定他们的潜在需求,以激发设计灵感,通过其作用于产品来从根本上消除盲人的自卑感、孤单感。Smart-Gloves将是一款多功能且支持后续开发升级的科技智能手套。

简介:摘要:Touch Mura在整个TFT-LCD制作流程中非常容易发生,并且严重影响产品性能。文章主要研究了液晶量、Sub PS设计、PS段差设计及工艺参数Total pitch对Touch Mura的影响。实验结果表明液品量的增加能够补偿敲击偏移,减轻 Touch Mura 不良;Sub PS的Z字形设计由于阻挡效应能够有效减轻 Touch Mura;Main PS和Sub PS的段差越大,Touch Mura margin越小;工艺参数Total Pitch 越接近设计值,Touch Mura 风险越小。所以在设计过程中优化液晶量和Main-Sub PS段差设计及 Sub PS设计能够有效减低Touch Mura 风险,此外,生产过程中对工艺参数 Total pitch的管控也至关重要。
