The response layer includes a material which is easy to decompose and release gas under irradiation of a laser with a preset wavelength. It can mitigate the effect of the transfer quality of microdevices due to the variations of laser spot.

The opening of the second PSR is larger than the pad open region of the first PSR.

A backlight structure and a display device are provided. The backlight structure includes a barrier wall pattern and light-emitting units. The barrier wall pattern includes openings and a barrier wall surrounding the openings, the openings are configured to define light regions; and the light-emitting units are distributed in the light regions.

Provided is a display apparatus that can suppress degradation of image quality caused by possible color drift. A display apparatus includes a board including a driving circuit based on a current amplitude modulation scheme, multiple first light emitting elements and multiple second light emitting elements two-dimensionally arranged on the board, and a wavelength correcting layer that is able to correct wavelengths of light emitted from the multiple first light emitting elements. The driving circuit is able to independently gamma-correct a first signal fed to the first light emitting element and a second signal fed to the second light emitting element.

A light-emitting substrate and a manufacturing method are provided. The light-emitting substrate includes a substrate and light-emitting devices arranged at intervals thereon. Light-shielding structure is at a gap between the light-emitting devices and shields light emitted from the light-emitting devices laterally. The light-shielding structure and light-emitting devices do not overlap in a target light-emitting direction of the light-emitting devices, or overlap in a target light-emitting direction of the light-emitting devices by being less than a width. Since the light-shielding structure is at the gap between the light-emitting devices, light emitted by the light-emitting devices laterally is shielded, avoiding light from irradiating other devices and causing light crosstalk. Light from the light-emitting devices in the target light-emitting direction is not shielded or not completely shielded, eliminating an adverse effect on light efficiency of the light-emitting devices, improving the light-emitting effect of the light-emitting surface of the light-emitting substrate.

The circuit board has a first surface and a second surface. The circuit board is provided with a first control unit, a first driver group, a second control unit, and a second driver group. The backlight module is disposed on the first surface of the circuit board. The plurality of light-emitting elements are disposed on the first surface of a circuit board. The panel is stacked on the backlight module. The first control unit is adapted to control the first driver group to drive at least one of the plurality of piezoelectric elements to vibrate, and the second control unit is adapted to control the second driver group to drive at least one of the plurality of light-emitting elements to emit light.
