A light emitting device, a display panel, and a display panel manufacturing method are provided in the embodiments of the present disclosure. The light emitting device includes a first electrode, and second electrode arranged around the first electrode, and the second electrode is symmetrically disposed with respect to the first electrode. A distance from each of points on the second electrode to a center point of the first electrode is equal. When the light emitting device is transferring, any point on the second electrode abuts the corresponding electrode, thereby reducing the difficulty in a mass transfer process of the light-emitting device.

Light emitting device, display panel, and display panel manufacturing method

A method of manufacturing an OLED back plate and an OLED back plate are provided. The method includes: providing a TFT substrate and forming an electrode layer on the TFT substrate; forming a pixel defining layer on the electrode layer by using a first mask, and forming a plurality of pixel units, each of the pixel units includes a light emitting area, and an inter-pixel area is formed between adjacent two of the pixel units; etching the electrode layer corresponding to the inter-pixel area; removing the pixel defining layer corresponding to the light emitting area to form a pixel opening; and forming a barrier block on adjacent two of the pixel defining layers of adjacent two of the pixel units by a second mask, and the barrier block does not completely cover the pixel defining layer.

Organic light emitting diode back plate and method of manufacturing same

An LED display screen, includes: a frame, modules disposed at a side of the frame and including an LED light board, and a non-display surface of the LED light board is provided with a first socket configured to be connected with a board-to-board connector; and a power box disposed inside the frame and located between the modules, with a control board connected with the LED light board via the board-to-board connector; wherein the control board comprises a main control board and at least one sub-control board, a surface of the sub-control board facing a surface of the LED light board is provided with a second socket configured to match with the first socket, each of the sub-control boards is fixed by an elastic mechanism and a bottom surface of the power box opposite to the LED light board.

LED display screen and display device

A display panel and a preparation method thereof, the display panel includes a substrate layer, a passivation layer, a plurality of color resisting units, a plurality of anodes, a pixel definition layer, a light emitting layer and a cathode. The present disclosure through makes at least one of the color resisting units partially cover a projection of the light emitting layer on the color resisting units to overcome the problem that part of the light emitted from the light emitting layer passing through the color resistance unit for adjusting a color gamut, and the brightness of part of the unadjusted light will not lost, thus, at last, the display panel has lack of display brightness due to adjusting the color gamut of the display and using the color resistance unit.

Display panel and preparation method thereof

A manufacturing method for an inkjet printing AMOLED display panel is disclosed. The method includes steps of: manufacturing a TFT backplane, and manufacturing an anode on the TFT backplane; manufacturing a spacer layer for isolating the anode from a pixel definition layer on the anode; manufacturing a pixel definition layer on the TFT backplane, and the pixel definition layer covers the spacer layer; patterning the pixel definition layer to form a notch on the pixel definition layer in order to expose the spacer layer; etching the spacer layer below the notch by an etching solution; and forming an ink layer on the anode by an inkjet printing method. The invention can improve the cleanliness of the anode surface in the AMOLED display panel, reduce the residue, and make the printed light-emitting layer easier to spread evenly, prevent the AMOLED display panel from displaying abnormality.
