Abstract

The invention discloses an alignment device for a metal mask plate. The alignment device for the metal mask plate comprises a dark box, an image pick-up device, an industrial personal computer, an evaporation plating host PC (Personal Computer), wherein the interior of the dark box comprises a platform, an OLED (Organic Light-Emitting Diode) substrate and a position sensor which are located on the platform; the OLED substrate is fixed on the platform through vacuum adsorption; the image pick-up device is arranged in a vacuum unit and is in signal connection with the industrial personal computer through a circuit; and the image pick-up device is used for acquiring alignment image information of the OLED metal mask plate and transmitting the alignment image information to the industrial personal computer through the circuit. According to the alignment device for the metal mask plate, disclosed by the invention, alignment image information of the OLED substrate is collected by adopting the CCD (Charge Coupled Device) camera and the alignment image information is transmitted to the industrial personal computer and is processed, and secondary alignment on the OLED substrate is realized by a processing signal and preset precision information, therefore the goal that the alignment precision of the OLED metal mask plate is increased is achieved.

Description

technical field [0001] The invention belongs to the field of OLED display technology, and in particular relates to an OLED metal mask alignment device. Background technique [0002] In flat panel display technology, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is a display device that causes organic materials to emit light through carrier injection and recombination. It is recognized by the industry as the third-generation display technology after liquid crystal display (LCD) due to its thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, high and low temperature resistance and many other advantages. Active OLED (ActiveMatrixOLED, AMOLED) is also called active matrix OLED. AMOLED can realize large size and high resolution by integrating a thin film transistor (TFT) and a capacitor in each pixel and maintaining the voltage by the capacitor. High-resolution panels are ...
