Light emitting device free of TFT and chiplet
A light emitting device is disclosed, including a first electrode layer, a second electrode layer, and an organic light emitting layer sandwiched between the first and second electrode layers. The second electrode layer is patterned to form a plurality of electrode patterns arranged with different densities. The organic light emitting layer is subjected to a color separation process to form a plurality of monochromatic blocks that correspond to the electrode patterns, respectively. The electrode patterns are divided into a plurality of electrode pattern groups arranged in an alternate manner. The electrode pattern groups display a same image, and a same voltage is applied to the electrode pattern groups at a same time. Alternatively, the electrode pattern groups display different images, and a same or different voltages are applied to the electrode pattern groups at different times. As such, the light emitting device generates grayscale, full-color, three-dimensional or dynamic images.
