Description

technical field

[0001] The invention relates to the field of display technology, in particular to a mask component and a manufacturing method thereof. Background technique

[0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display is a display with an autonomous light-emitting function. OLED displays are widely used in the display industry due to their thin thickness, light weight, active light emission, fast response, wide viewing angle, rich colors, high brightness, low power consumption, and high and low temperature resistance. In the manufacturing process of the OLED display, the OLED material can be evaporated on the base substrate by using an evaporation machine with a mask assembly to form an organic light-emitting pattern on the base substrate to obtain an array substrate.

[0003] The current mask components usually include: a metal frame, a metal shielding sheet mask and a fine metal mask (English: Fine Metal Mask;...

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] The OLED display device includes a plurality of pixels arranged in a matrix, and the OLED display device can be divided into an active matrix organic light emitting diode (English: Active Matrix / Organic Light Emitting Diode; abbreviation: AMOLED) display device and an OLED display device according to the driving method of its pixels. A source matrix organic light-emitting diode (English: Passivematrix Organic Light-Emitting Diode; abbreviation: PMOLED) display device. OLED display devices include OLED displays. At present, an evaporation machine is generally used to cooperate with a mask assembly to evaporate OLED materials on the substrate by evaporation to form an organic light-emitting pattern on the substrate to obtain an arr...
