    Abstract: An imaging apparatus includes an imaging element, an imaging driver, a controller, and a memory. The imaging driver is configured to drive the imaging element. The controller is configured to detect a flicker in an image captured by the imaging apparatus. The memory is configured to, in response to the flicker being detected, store data on a characteristic of the flicker, a first frame rate, and a first shutter speed of the imaging element.

    Abstract: A display device according to an embodiment includes a pixel and a bank. The pixel includes sub-pixels and an emission area including sub-emission areas corresponding to the sub-pixels. The bank surrounds the emission area. The pixel includes electrodes disposed in each of the sub-emission areas, at least one light emitting element disposed in each of the sub-emission areas, and bank patterns disposed under the electrodes, the bank patterns overlapping a portion of the electrodes. The bank patterns include a first bank pattern including a first valley, the first bank pattern being disposed in a first edge area of the emission area in a first direction. The bank patterns include a second bank pattern including a second valley, the second bank pattern being disposed in a second edge area of the emission area in the first direction.

    IPC: G09G3/32

    Abstract: Provided is a gate driver comprising an inverter inverting a start signal to generate an inverted start signal, a first driver including a first stage generating a bias gate signal to initialize a light emitting element of each of pixels in response to the inverted start signal, and a second driver including a second stage generating a write gate signal to apply data voltages to the pixels in response to the start signal. Accordingly, the gate driver may generate a plurality of gate signals using one start signal. In addition, since the gate driver generates a write gate signal and a bias gate signal using one start signal, a bias operation and a light emitting element initialization operation may be performed in a self-scan period without adding the start signal. Further, a size of the gate driver may be reduced, and accordingly, the gate driver may be efficiently disposed.
