新型柔性显示薄膜的设计

New design of flexible light distribution film

  • 摘要: 由于采用发光二极管(LED)制作显示薄膜,所以可以改善常规显示屏有缝拼接,刷新频率低,应用场合相对窄的缺点,如果显示薄膜的衬底材料为聚碳酸酯(PI)薄膜,薄膜后的印刷电路板(PCB)也做成柔性的,那么显示屏就是柔性LED显示屏了,可以应用到更多的场合。显示屏的核心设计是显示薄膜的设计,此设计制作的柔性显示薄膜,要求像素间距为1 mm,折弯半径小于10 cm。最后采用lighttools专业软件进行仿真分析,并进行了一系列具体实验,测出这种像素间距为1 mm的样品折弯半径为3.1 cm,可以看出:实验结果和仿真分析有较大吻合性, 说明这种设计有充分的可行性。

     

    Abstract: A new design method of flexible display film was proposed. Because of the use of light-emitting diodes (LED) chips to make display screens, it can improve the shortcomings of conventional display screens, such as seamless splicing, low refresh frequency and relatively narrow application.If the substrate material of the display film is polycarbonate (PI) film, the printed circuit board (PCB) behind the film is also flexible, so the display screen can be flexible and can be applied to more occasions. One of the core designs of the display screen is the design of the display film. In the designed and manufactured flexible display film, the pixel spacing is 1 mm and the bending radius is less than 10 cm, We need to set up isolation layer and phosphor layer, that is on the top and the other side. Finally, the simulation analysis was carried out by using the professional software of lighttools, and a series of specific simulation analysis and experiments were carried out, the bending radius of the sample with 1 mm pixel spacing is 3.1 cm. It can be seen thatthe experimental results are in good agreement with the simulation analysis, proving the design is feasible.
