A processing device for a spliced ​​oled flexible liquid crystal display

Abstract

The invention discloses a processing device for a spliced ​​OLED flexible liquid crystal display, comprising: an operation box supported on the ground by a bracket; a transition room installed on one side of the operation box, and the transition room and the operation box can be Open or close through the sealing structure, so that the sealing structure can be opened in the operation box to take out the items in the transition chamber; there are two opening and closing mechanisms, which are installed on both sides of the transition chamber, and the protective gas is filled through the operation box and the transition chamber Compared with the relative mass of the air under the same pressure premise, the two opening and closing mechanisms located at the top or bottom of the transition chamber can be opened respectively, so that objects can be put into the transition chamber. The opening and closing mechanism further reduces the loss of protective gas, reduces the inflow of air and water vapor, reduces the cost of inert gas in the production process, reduces the energy consumption of circulation equipment, and reduces the production cost of OLED displays.

Description

technical field [0001] The invention relates to the technical field of OLED liquid crystal displays, in particular to a processing device for a spliced ​​OLED flexible liquid crystal display. Background technique [0002] OLED is also known as organic electro-laser display and organic light-emitting semiconductor. OLED is a current-type organic light-emitting device, which is a phenomenon of luminescence caused by carrier injection and recombination. Under the action of an electric field, the holes generated by the anode and the electrons generated by the cathode will move, inject into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons will be generated. , so that the luminescent molecules are excited to finally produce visible light.

Problems solved by technology

[0003] During the processing of the OLED display, it needs to be packaged. The packaging of the OLED is mainly to isolate the light-emitting device from the external environment, prevent the intrusion of moisture, harmful gases (oxygen, etc.), dust and rays, prevent external damage, and stabilize the device. The various parameters of the OLED, thereby improving the service life of the OLED, are usually operated in a glove box filled with an inert gas during the packaging process, and the water vapor and oxygen content in the inert gas in the glove box are lower than . A gas circulation mechanism is added to the box and transition chamber of the glove box to continuously circulate the gas in the box during the working period of the glove box to ensure that the gas is in a relatively dry state. When packaging in the glove box, it is necessary to put the tool into the box, first Open the door of the transition chamber, then put the tools and devices into the transition chamber, then close the door of the transition chamber, circulate the gas in the transition chamber until the oxygen and water vapor are below .mmp, open the doors of the box and the transition chamber, and place After the tools or devices are put into the box, the door between the box and the transition chamber is closed in reverse. The access and removal of the devices and tools have to go through the two doors of the transition room. However, the glove box is filled with different When the type of protective gas is used, the opening position of the transition chamber is the side of the transition chamber. During the process of opening and closing the transition chamber, part of the air will directly enter the transition chamber, and at the same time, the shielding gas in the transition chamber will escape into the air, increasing the The cost of inert gas in the production process, in addition, the energy consumption of the equipment for removing water vapor and oxygen in the circulation equipment also increases simultaneously, which increases the production cost of OLED displays
