具有金属网格的碳纳米材料被用作液晶显示器（LCD）的透明导电电极，开发了一种不含氧化铟锡（ITO）的设备。我们用碳纳米管和石墨烯电极制备了液晶显示器；然而，具有CNT电极的器件的工作电压较高。采用石墨烯电极的器件具有良好的性能，但不如采用ITO电极的器件。为了提高器件性能，我们将金属网格应用于碳纳米材料，以制造低薄层电阻的透明电极。具有石墨烯和金属网格透明电极的器件的阈值电压低至0.23 V/μm，与具有ITO电极的典型LCD的阈值电压相似。结果表明，石墨烯和金属网格的混合透明导电薄膜可以替代 ITO，用于开发无 ITO 的 LCD。
Carbon nanomaterials with metal grids were used as transparent conductive electrodes for liquid crystal displays (LCDs) to develop an indium tin oxide (ITO)-free device. We prepared LCDs with CNTs and graphene electrodes; however, the working voltage of the device with the CNT electrodes was high. The device with graphene electrodes had good performance, but not as good as devices with ITO electrodes. To improve the device performance, we applied a metal grid to the carbon nanomaterial to create low sheet-resistance transparent electrodes. The device with the graphene and metal grid transparent electrodes had a threshold voltage as low as 0.23 V/µm, which is similar to that of typical LCDs with ITO electrodes. The results show that a hybrid transparent conductive film with graphene and metal grid could be an alternative to ITO for developing ITO-free LCDs.
