Abstract: A light-emitting assembly contains a light-emitting diode and a driving circuit configured to provide a driving current for driving the light-emitting diode to emit a light. The driving circuit comprises a thermistor, which is coupled to the light-emitting diode and configured to have an electrical resistance thereof altering with a change of a temperature of the light-emitting assembly to thereby adjust an intensity of the driving current. The thermistor can be a metal thermistor, a negative-temperature coefficient thermistor, a critical-temperature thermistor, or a positive-temperature coefficient thermistor. The light-emitting assembly can automatically adjust a brightness of the light emitted by the light-emitting diode to be within an expected range, causing an improved working life and reliability. The light-emitting assembly can be employed in a lighting device or a display panel.

Abstract: Embodiments of the present invention disclose a display panel and an encapsulation method thereof, and relate to the field of display technology. The display panel comprises a first substrate and a second substrate which are disposed in opposition to each other. The first substrate and the second substrate are encapsulated by a sealant. In a non-display area of the display panel, a first adsorption layer is disposed on one of the first substrate and the second substrate, and a second adsorption layer is disposed on the other of the first substrate and the second substrate. The first adsorption layer and the second adsorption layer may be attracted to each other by magnetic force. Embodiments of the present invention can effectively avoid the separation of the first substrate and the second substrate due to the stress released during the process of melting the sealant, thereby improving the problem of poor encapsulation caused thereby.
