摘要： Methods and devices useful in compensating for VDD and VTH variations in a micro light-emitting diode (micro-LED) display are provided. By way of example, an LED driver includes a first transistor having a first source coupled to an upper voltage rail (VDD), a first gate, and a first drain. The LED driver includes a second transistor having a second source coupled to the first drain of the first transistor, a second gate, and a second drain coupled to the LED. The second transistor is configured to receive the drive current signal from the first transistor and supply the drive current signal to the LED. The LED driver includes compensation circuitry configured to adjust the drive current signal such that the drive current signal is independent of the upper voltage rail (VDD) and a threshold voltage (VTH) of the first transistor or the second transistor.

摘要： A method of forming liquid crystal cell for a color display device includes forming a liquid crystal layer and a prism structure between top and bottom substrates. Forming the prism structure includes forming a lens shaped die, coating a low refractive index resin on the lens shaped die, pasting the lens shaped die to the top substrate, and irradiating the coated low refractive index resin so as to set the low refractive index resin and form a low refractive index layer. The lens shaped die is removed from the low refractive index layer, a high refractive index resin is coated on the low refractive index layer by use of a planarizing die. The coated high refractive index resin is irradiated so as to set the high refractive index resin and form a high refractive index layer, and the planarizing die is removed from the high refractive index layer.
