等离子显示器中的潘宁气体在放电过程中会产生近红外线、氖黄光，干扰遥控器等设备，影响观看效果，需安装滤光膜。文章对以酞菁类、二亚铵类为近红外吸收染料的PDP滤光膜进行了对比研究，实验结果表明，酞菁类、二亚铵类滤光膜具有良好的耐湿热、耐高温性能，二亚铵类滤光膜相对于酞菁类滤光膜具有较好的光稳定性能，且可见光区透过率可达到60%以上，适合应用于高透过率PDP滤光膜。

The penning gas of PDP will produce near-infrared ray, neon yellow light during the discharge process, and affect their performance, the PDP filter must be used to prevent them. The properties of PDP filter which near-infrared ray absorbing dye used phthalocyanine or diimonium was investigated. The results show that the PDP filter of phthalocyanine and diimonium have good resistance to heat and high temperature performance. The PDP filter of diimonium is better than the PDP filter of phthalocyanine on the property of light stability, and visible light transmittance of more than 60%, so it is suitable for high transmittance filter films.
