Abstract

The invention discloses a flat heating device, comprising an upper pressure board, a lower bottom board and a heating piece, wherein, the upper end surface of the lower bottom board is provided with a first installation groove and a second installation groove which are distributed in a step shape; the first installation groove is matched with the upper pressure board; the second installation groove is arranged in the first installation groove and matched with the heating piece; the upper pressure board is installed in the first installation groove and fixedly connected with the lower bottom board; the heating piece is installed in the second installation groove and arranged between the upper pressure board and a lower pressure board; and the heating piece comprises resistance wires, an insulation film and electrodes, the resistance wires are sealed in the insulation film and are in regular bent shapes, and two ends of the resistance threads are electrically connected with a positive electrode and a negative electrode correspondingly. Compared with the prior art, the flat heating device has simple structure, low cost, easy achievement, uneasy damage, saved space and uniform heating.

Description

technical field [0001] The invention relates to a flat panel heating device, in particular to a flat panel heating device providing a surface heat source for a flat panel. Background technique [0002] OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminescence Display (OELD). Because of its lightness, power saving and other characteristics, it has always been favored by people in the industry. OLED display technology is different from traditional LCD display methods. It does not require a backlight, and uses very thin organic material coatings and glass substrates. When an electric current passes through, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, has a larger viewing angle, and can significantly save power. It is regarded as one of the most promising products in the 21st century. [0003] However, organic light-emitting display technology still has ...
