Problems solved by technology

The disadvantage is that this kind of electrode can only increase the contact area of ​​the interface, and cannot effectively use the space of the flat panel display to produce a low-resistance display electrode.
[0008] Although these inventions can improve the derivation efficiency in other fields such as organic solar cells and organic light-emitting diodes, they cannot be applied to the lead parts that require extremely low resistance in display fields such as liquid crystal and electronic paper.
The main reason is that the resistance of the above-mentioned ITO display electrode is still very large when there is a slight change in the electrode. In practical applications, it is difficult to manufacture electrodes with a thickness in the order of microns, and it is impossible to reduce the lead resistance.
The disadvantages of increasing the thickness of the ITO film without limit are: as the thickness of the ITO film increases, the coating time is significantly longer, and the precision and production time of the photolithography process are difficult to control, and mass production cannot be achieved.
Utilizing the metal thin film method is a subtractive process, and the raw materials, environmental burden and energy consumption are very high

Abstract

The invention discloses a stereo display electrode which comprises a transparent film display electrode and a stereo auxiliary electrode which is connected with the transparent film display electrode. The stereo display electrode is characterized in that the stereo auxiliary electrode comprises a formed insulating layer and a sealed insulating layer fixed at the upper end of the formed insulating layer, wherein a groove used for containing an electric conduction part is formed in the formed insulating layer, and the stereo auxiliary electrode is communicated with the transparent film display electrode through at least one communication hole which is formed at the lower end of the formed insulating layer. The invention further discloses a manufacturing method of the stereo display electrode. According to the stereo display electrode, the features of low resistance and high transparence are achieved, and low resistance, width minimization, even electric conductivity and flexibility and complete separation from display materials are achieved through the adjustment of thickness and material property of the stereo auxiliary electrode. The stereo display electrode can effectively reduce the resistance of an electrode, fully utilize redundancy space of an inner electrode of a display, and improve the resolution rate, refresh rate and contrast ratio of the display.
