This invention relates to a display panel and its manufacturing method. The display panel includes a driving backplane and a plurality of light-emitting devices located on one side of the driving backplane. Each light-emitting device includes: a first electrode electrically connected to the driving backplane, with the first electrodes in each light-emitting device being independently disposed; an epitaxial structure, with the epitaxial structure in each light-emitting device being independently disposed on the side of the first electrode away from the driving backplane, and each epitaxial structure including a first semiconductor layer, an active layer, and a second semiconductor layer sequentially stacked along a direction away from the driving backplane; and a second common electrode electrically connected to the driving backplane, and the second common electrode including a transparent conductive film, which is in contact with the second semiconductor layer in each epitaxial structure. With the same number of pixels, the light-emitting devices with the above structure improve the transparency of the display panel; similarly, with the same transparency, more light-emitting devices with the above structure can be arranged, thereby increasing the PPI of the display panel.

The invention discloses a wax mold cleaning agent as well as a preparation method and application thereof. The wax mold cleaning agent comprises the following raw materials in parts by mass: 100 parts of purified water; 1 to 8 parts of OP-10; 1 to 8 parts of Tween-80; 3 to 12 parts of polyethylene glycol 200; 3 to 12 parts of a silane modified coupling agent; 0.4 to 1.2 parts of polyether modified silicone oil; 1-7 parts of benzyl alcohol; 0.1 part to 0.7 part of hydroxyethyl cellulose; 0.1 part to 1.3 parts of isothiazolinone; and 0.3 to 2.4 parts of glycerol. The cleaning effect of the wax mold cleaning agent is superior to that of a traditional organic solvent, the wax mold size precision is not affected, non-metal parts of equipment are not corroded, meanwhile, the production cost and the wastewater treatment difficulty are greatly reduced, and green, safe and efficient wax mold cleaning is achieved.

The utility model discloses a continuous graphitization on-line measuring system which comprises an on-line graphitization degree detection device and a control system, the on-line graphitization degree detection device comprises a mechanical arm, a gripper, a sampler, a stirrer, a standard sample storage device, a detection container, a balance and a powder diffractometer, the output end of the mechanical arm is respectively connected with and drives the gripper, the sampler, the stirrer and the standard sample storage device to act, and the control system is respectively connected with the mechanical arm, the balance and the powder diffractometer, so that a graphite sample is grabbed by the sampler and then is put into the detection container to be mixed with a standard sample; and transferring to the powder diffractometer to detect the graphitization degree of the graphite sample. According to the utility model, the performance of the continuous graphitized material can be detected on line in real time, so that key indexes of the graphitized material can be timely controlled, the fluctuation of the indexes in a reasonable range is reduced, and the qualified rate of products is improved.
