Title: Jun-Kai Chang: Innovator in Pixel Structure Fabrication

Introduction

Jun-Kai Chang is a notable inventor based in Chiayi, Taiwan. He has made significant contributions to the field of pixel structure fabrication, holding a total of 3 patents. His work focuses on enhancing the technology behind thin film transistors (TFTs), which are crucial for modern display technologies.

Latest Patents

Chang's latest patents include innovative methods for fabricating pixel structures. One of his patents describes a process where a gate is formed on a substrate, followed by the creation of a gate insulation layer. A channel layer, source, and drain are simultaneously formed on the gate insulation layer above the gate. This configuration results in a thin film transistor (TFT). Additionally, a passivation layer is applied, along with a black matrix that features contact openings above the drain and color filter containing openings. A color filter layer is then formed through inkjet printing, followed by the application of a dielectric layer. The dielectric layer and passivation layer are patterned to expose the drain, culminating in the formation of a pixel electrode that is electrically connected to the drain.

Another patent outlines a similar method, where a gate and gate insulation layer are formed on a substrate. A channel layer is created on the gate insulation layer, and a conductive layer is added. A black matrix with a color filter layer accommodating opening is formed on the conductive layer. The conductive layer is patterned to create a source and drain on the channel layer, and a color filter layer is formed within the accommodating opening through inkjet printing. This method also includes the formation of a dielectric layer and a pixel electrode connected to the drain.
