Back plate, backlight module, display device, and assembly method of backlight module

The present disclosure discloses a printing machine. The printing machine includes a carrying platform for carrying a to-be-printed board, a frame above the carrying platform, a roller-shaped screen printing plate with printing graphic meshes, and an ink supply device within the roller-shaped screen printing plate. The roller-shaped screen printing plate is mounted to the frame in a manner that the roller-shaped screen printing plate is capable of rotating relative to the carrying platform.

Printing machine

The present disclosure provides a backlight source module including a backplate; a bottom reflective sheet, a light guide plate and an optical sheet which are stacked on the backplate in that order; and a frame disposed at peripheral edges of the backplate for holding the bottom reflective sheet, the light guide plate and the optical sheet on the backplate. The backlight source module further includes a gap adjusting element configured to adjust a gap between the optical sheet and the frame in a direction perpendicular to the backplate.

Backlight source module and display device

Embodiments of the present invention provide a light guide plate for a backlight module. The light guide plate includes: a body comprising: a first surface; a second surface which is opposite to the first surface and serves as a light output surface; and a side face; and a groove formed inside the body and having an opening located in the side face. The groove is configured to accommodate an optical film.

Light guide plate and manufacturing method thereof, backlight module, and display apparatus

The present invention relates to a light guide plate (LGP) capable of bidirectional focusing via a bidirectional micro-transmissive layer, a fabrication method of the LGP, an extrusion equipment, a backlight module and a display device. The LGP comprises a LGP substrate, the LGP substrate comprises at least one incident surface for receiving a light beam and one outgoing surface connected to the incident surface, a bidirectional micro-transmissive layer is provided in the LGP substrate, the bidirectional micro-transmissive layer comprises a plurality of micro-transmissive points having biconvex surfaces. According to the principle that convex lens converges light, the design of micro-transmissive points having biconvex surfaces causes several scattered light beams having different directions that enter the micro-transmissive points to be converged, which effectively improves the brightness of the outgoing surface of the LGP, thereby improving the brightness and definition of images displayed in the liquid crystal panel.

Light guide plate and fabrication method thereof, extrusion equipment, backlight module and display device

A light source assembly, a backlight and a display device are provided. The light source assembly comprises a bar-shaped light source unit, which comprises an organic light-emitting diode for emitting light and has a light outgoing side; and a light concentration bar, which has a light incidence surface and a light outgoing surface opposite to each other, the light incidence surface being disposed at an outer side of the light outgoing side of the light source unit and matching with the light outgoing side in size, and the light outgoing surface matching with a light incidence side of a light guide plate in size.

Light source assembly, backlight and display device

The present invention relates to an array-type double-side light-emitting device, a manufacturing method thereof and a double-side display device. The array-type double-side light-emitting device comprises: a first protective layer, a first fluorescent layer or quantum dot layer, an array of first transparent conductive layers, a first anisotropic conductive adhesive layer, an array of light-emitting wafers, a second anisotropic conductive adhesive layer, an array of second transparent conductive layers, a second fluorescent layer or quantum dot layer and a second protective layer, which are attached together sequentially.

Array-type double-side light-emitting device and manufacturing method thereof and double-side display device

Embodiments of the present invention disclose a reflective film, a backlight module comprising the reflective film and a display apparatus comprising the backlight module. A row of low-reflection dots are disposed on a side of a surface of the reflective film, and regions of the surface of the reflective film corresponding to the low-reflection dots have smaller reflectivity with respect to the incident light from an LED light strip disposed at a side of the row of the low-reflection dots than other regions of the surface of the reflective film with respect to the incident light from the LED light strip. The regions of the reflective film directly facing the LED are changed into low-reflection regions, in which the reflectivity is reduced. Therefore the alternate bright and dark phenomenon at light incident side is reduced or eliminated and display quality of the display apparatus is further improved.
