Abstract

The invention provides a combination type mask plate and a manufacturing method thereof. The combination type mask plate comprises a mask frame (1), a plurality of first picking plates (2) and a plurality of second picking plates (3). The first picking plates (2) and the second picking plates (3) are overlapped and form a mesh-shaped structure with a plurality of film-forming holes (4). The thicknesses of the first picking plates (3) and the second picking plates (4) are equal. First grooves (21) which penetrate through the widths of the first picking plates (2) are formed in the portions, overlapped with the second picking plates (3), of the first picking plates (2). Second grooves (31) which penetrate through the widths of the second picking plates (3) are formed in the portions, overlapped with the first picking plates (2), of the second picking plates (3). The first picking plates (2) and the second picking plates (3) are embedded and overlapped through the first grooves (21) and the second grooves (31), and the upper surfaces and the lower surfaces of the first picking plates (2) and the second picking plates (3) are placed on the same plane respectively.

Description

technical field [0001] The invention relates to the field of manufacturing organic light emitting diode displays, in particular to a combined mask plate and a manufacturing method thereof. Background technique [0002] Organic light emitting diode display (Organic Light Emitting Diode, OLED) is a promising flat panel display technology, it has very excellent display performance, especially self-illumination, simple structure, ultra-thin, fast response, wide Viewing angle, low power consumption, and flexible display are known as "dream display". In addition, the investment in its production equipment is much smaller than that of TFT-LCD. It has been favored by major display manufacturers and has become the No. 1 display technology in the field of display technology. The main force of the three generations of display devices. At present, OLED is on the eve of mass production. With the further deepening of research and the continuous emergence of new technologies, OLED display...
