Abstract: Laser emission based microscope devices and methods of using such devices for detecting laser emissions from a tissue sample are provided. The scanning microscope has first and second reflection surfaces and a scanning cavity holding a stationary tissue sample with at least one fluorophore/lasing energy responsive species. At least a portion of the scanning cavity corresponds to a high quality factor (Q) Fabry-Pérot resonator cavity.

The second reflection surface and/or the lasing pump source are translatable with respect to the stationary tissue sample for generating a two-dimensional scan of the tissue sample. Methods for detecting multiplexed emissions or quantifying one or more biomarkers in a histological tissue sample, for example for detection and diagnosis of cancer, or other disorders/diseases are provided.

Abstract: A laser whose emission is modulated by ultrasound is presented. The laser is usually micron-sized. In response to ultra-sound modulation, the laser emission increases and decreases. Such a change in emission can be detected by external optical detectors. This type of laser can be used as a new type of imaging modality, in which laser emission in combination with sound waves or ultra-sound waves, is used for imaging Laser emission has a much narrower spectral linewidth and stronger intensity than fluorescence and therefore is able to achieve higher sensitivity, whereas sound waves are used to provide a better spatial resolution of the laser emission from the laser. In ultrasound modulated laser based imaging, multiple lasers can be placed inside cells or tissues.

Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.
