OLED (Organic Light-Emitting Diode) is a phenomenon in which organic materials emit light through carrier injection and recombination under the influence of an electric field. It is a technology that converts electrical energy into light energy using organic light-emitting materials, encompassing both Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). PMOLED is characterized by its low production cost, low mold opening cost, and mature production process. Its grayscale, resolution, and image quality are controlled by current, and the products are primarily monochrome or multicolor, targeting the low-resolution and small-size market, making it ideal for customized product development. On the other hand, AMOLED offers vivid colors, fast response times, low driving voltage, and thinner display panels, enabling more compact designs and space savings.

JINJIA specializes in the research, development, and production of 0.6-5 inch AMOLED and PMOLED displays. Additionally, we provide optical bonding services with touch screens to meet diverse customer display requirements.
