Latest Patents

Yen-Lin Wei holds a patent for a "Current-scaling active thin film transistor circuit structure for pixel of display device." This invention features an active TFT circuit structure that includes a current source, a data line, a scan line, a direct current voltage source, capacitors, and four transistors. The capacitors are arranged in a cascade structure. During the ON-state, two transistors are activated based on the voltage from the scan line, allowing data current from the current source to flow through the data line and one of the opened transistors, ultimately reaching an emitting light element. When the pixel circuit transitions from ON- to OFF-state, the voltage at the node between the storage capacitors decreases due to the feed-through effect of one of the storage capacitors, which reduces the driving current of the emitting light element. This design achieves the current scaling function, enhancing the performance of display devices.
