Abstract: The present invention teaches a GOA circuit driving method and a GOA circuit driving device. Through the configuration of a buffer capacitor electrically connected to the level shift IC, the level shift IC connects to the buffer capacitor and switches to the transition level during shifting the target clock signals from high to low level or from low to high level. Through the buffer capacitor, the present invention is able to keep the transition level always equal to one half of the sum of the low voltage and the high voltage, thereby maximizing reduction of power consumption and feedthrough effect of the GOA circuit.

Abstract: The present invention belongs to the technical field of lasers and provides a dual-chirped spectral optical parametric amplifier and an amplification method. A femtosecond laser assembly is configured to generate simultaneous pump and signal waves which successively pass through an input grating and an input collimator respectively. The various spectrum components of both the pump and the signal waves linearly disperse and focus on respective focal points, and present spatial chirps with opposite frequency gradients in the respective focal planes. A full-spectrum optical parametric amplification of the signal wave with the pump wave is performed via a fan-out periodically poled crystal, resulting an ultrabroad idler wave. The ultrabroad idler wave is separated from the hybrid waves via an optical splitter, and then passes successively through an output collimator and an output grating, and is Fourier transformed from frequency domain to temporal domain.

Abstract: Optical sensing is provided with a large sensing area in a thin package. For example, embodiments can operate in context of an under-display optical fingerprint sensor integrated into an electronic device, such as a smartphone. Responsive to reflected probe light passing through a display module, a reflective structure is configured to redirect the reflected probe light onto a refractive structure, and the refractive structure is configured to converge the reflected probe light into an input aperture of an optical sensor for detection. Some embodiments operate in context of an enhancement panel having micro-prism structures that tend to blur the reflected probe light. In such context, embodiments are configured for off-axis detection to prefer light passing through only certain micro-prism faces, thereby mitigating blurring.
