Abstract: A display panel including a wavelength conversion structure that includes a base structure including partition walls that define a first space and a second space, a first quantum dot composite disposed in the first space, and a second quantum dot composite disposed in the second space. The height of the partition wall is greater than or equal to about 5 micrometers and less than or equal to about 50 micrometers, and the first quantum dot composite provides a first top surface and the second quantum dot composite provides a second top surface. A production method for making the wavelength conversion structure uses a first ink composition that includes first quantum dots and a first matrix, and a second ink composition that includes second quantum dots and a second matrix.

Abstract: An electronic device includes a first substrate, a plurality of light emitting elements each having a horizontal length and a vertical length which are less than or equal to about 10 micrometers (?m), each of the plurality of light emitting elements being disposed on the first substrate, a quantum dot color filter layer disposed on the plurality of light emitting elements, and a first overcoat layer between a plurality of light emitting elements and the quantum dot color filter layer. The quantum dot color filter layer includes a plurality of quantum dot color filters partitioned by a plurality of first partition walls so as to be overlapped with the plurality of light emitting elements, respectively.

Abstract: This invention is in regards to a multiplex brush. The brush is composed of three types of visible bristles, allowing the users to feel more aware of its effectiveness and difference compared to when using single-type bristle brushes. The straight bristles, 1stwavy bristles and 2ndwavy bristles are planted together so the brush would have more grip. This is in regards to a multiplex brush with 1stwavy bristles and 2ndwavy bristles that are different in the degree and number of curves they have so the brush would allow hairs with different thickness and texture can all be styled easily, while maintaining its optimal condition.

The straight bristles, 1stwavy bristles and 2ndwavy bristles are planted together so the brush would have more grip. This is in regards to a multiplex brush with 1st wavy bristles and 2nd wavy bristles that are different in the degree and number of curves they have so the brush would allow hairs with different thickness and texture can all be styled easily, while maintaining its optimal condition.

Abstract: A rotatable roll brush that despite combing tangled hair, the hair does not get removed due to the rotation of the brush body part, and when a combing action is required without the rotation of the body part, the brush can be converted and used as a regular brush.
