The present disclosure relates to the field of display technology, and provides a display module and a display device. The display module includes a first display sub-panel, where the first display sub-panel includes: a first display sub-panel including a plurality of first pixel units; and a second display sub-panel arranged at a light-entering side of the first display sub-panel and including a plurality of second pixel units. Each second pixel unit corresponds to at least one first pixel unit, an orthogonal projection of each second pixel unit onto the first display sub-panel coincides with the corresponding first pixel unit, and the second display sub-panel is a vertical-electric-field-type liquid crystal display panel.

The present disclosure provides a quantum dot color filter, a fabrication method thereof, a display panel and a display device, and belongs to the field of display technology. The quantum dot color filter of the present disclosure includes a quantum dot functional layer configured to emit light of a certain color under excitation of excitation light. The quantum dot functional layer has a hollowed-out portion, which exposes a side surface of the quantum dot functional layer, so that the excitation light is able to arrive at the side surface.

A light-concentrating device, a light-concentrating display screen, and an electric product are provided. The light-concentrating device includes a light-concentrating plate. The light-concentrating plate includes dimming units, each dimming unit including a house, the house being filled with first light-transmissive liquid and second light-transmissive liquid insoluble with each other. Light may be refracted when passing through the interface between the first light-transmissive liquid and the second light-transmissive liquid. Adjustment electrodes are provided on sides of the house, and a common electrode layer is provided at an end of the house. The voltages may be applied between the common electrode layer and the adjustment electrodes on the sides of the house.

A light emitting panel and a display device are provided. The light emitting panel includes a first substrate, an adhesive layer, a second substrate, and a convex portion. The first substrate includes a light emitting region and a peripheral region surrounding the light emitting region. The adhesive layer is disposed on the peripheral region of the first substrate and surrounds the light emitting region. The second substrate is disposed on the adhesive layer. The convex portion surrounds the adhesive layer and is disposed on a first sidewall of the adhesive layer away from the light emitting region. This can avoid cutting the adhesive layer, thereby avoiding poor peeling and improving product yield.

According to an embodiment, a display device comprises a frame defining an opening, a grip extending from the frame, and a display panel which is held by the frame and whose background is visually recognizable. Further, the opening includes a region surrounded by an inner edge of the frame and the display panel.

A backlight assembly and its formation method, and a display apparatus are provided in the present disclosure. The formation method includes a circuit board; a plurality of light-emitting elements, disposed at a side of the circuit board; and a light guide element, configured to transmit light emitted from the plurality of light-emitting elements to a display element according to a preset light-guiding path. The backlight assembly transmits the light emitted from the light-emitting elements to the display element according to the preset light-guiding path through the light guide element, which improves the utilization rate of the light emitted from the light-emitting elements and emits higher brightness backlight through relatively low energy consumption.

A light control member includes a light control substrate including a surface, and a scalene prism disposed on the light control substrate. The scalene prism includes a first side surface extended at a first angle with respect to the surface of the light control substrate, and a second side surface extended at a second angle with respect to the surface of the light control substrate, the second angle being greater than the first angle. The light control member includes an etching stopper disposed on the scalene prism, and at least one absorption pattern disposed on the etching stopper on the second side surface of the scalene prism.

The present disclosure relates to an electronic element module including a printed circuit board including a first insulating layer having a plurality of first openings, and a build-up structure disposed on one surface of the first insulating layer and having a first through-portion, wherein the plurality of first openings are disposed in the first through-portion on a plane; a conductive adhesive disposed in at least a portion of each of the plurality of first openings; and a first electronic element disposed in the first through-portion, and having a plurality of first electrode pads disposed. At least a portion of each of the plurality of first electrode pads is disposed in the plurality of first openings.

A display device is disclosed. The display device includes a first substrate, a frame positioned in the rear of the first substrate, a second substrate opposite the first substrate and positioned between the first substrate and the frame, the second substrate having an area less than an area of the first substrate, and a member layer electrically connected to the first substrate and extended toward the frame.

Provided is an optical apparatus that is capable of switching between a state in which the optical apparatus can reflect light and a state in which the optical apparatus can output light and suppressing deterioration of display quality of a light reflection image. The optical apparatus includes: a light emitting device having a light emitting surface; an absorption type polarizing plate disposed opposite to the light emitting surface of the light emitting device; a liquid crystal optical element disposed between the light emitting device and the absorption type polarizing plate; a reflection type polarizing plate disposed between the light emitting device and the liquid crystal optical element; and an adhesive layer disposed on a surface of the reflection type polarizing plate that faces the light emitting device.
