【摘要】 等离子体显示器面板的电磁屏蔽膜,既要满足对规定的电磁辐射波段进行屏蔽的要求,又需要有良好的可见光透过率和对非三基色波段的光的吸收能力,以提高图象画面的显示质量。本文通过实验的方法,在某商品屏和样品屏上分别采用进口与国产EMI屏蔽膜进行测量对比,结果表明二者的EMI屏蔽膜对电磁辐射的屏蔽效果相当,基本都能将规定的不同频段的电磁辐射降到限值以下,而对于非三基色波段的光的吸收能力,进口EMI屏蔽膜的吸收效果要好于国产EMI屏蔽膜的吸收效果。更多还原

【Abstract】 The physical properties,including the transmittance of visible light,absorption of interference lights,and shielding of electromagnetic radiation,of various kinds of electromagnetic interference shielding(EMI) films,made in China and abroad,used in plasma display panel (PDP),were experimentally characterized and compared with a commercial PDP panel and a lab-made test panel.The results show that when it comes to shielding of electromagnetic radiation in different wavebands,both the imported and China made EMI films meet the technical requirements.However,the imported EMI films outperform the domestic ones in absorption of interference lights.We conclude that there is much room for improvement for EMI films grown in China.更多还原
