Problems solved by technology
However, when the roller bonding method is applied to the 3D curved surface cover plate bonding, the product is prone to produce defects such as Line Defect (line defect) at the curved edge. After analysis and measurement, it is considered that the roller exerts too much pressure on the flexible OLED panel at the edge. Large, resulting in damage to the flexible OLED panel

The embodiments of the present invention disclose a device for attaching a flexible OLED (Organic Light Emitting Diode) panel to a curved cover plate. The device includes an upper workbench, a lower workbench, a roller, a piezoelectric conversion module, a processing module and an adjustment module; the piezoelectric conversion module is used for detecting pressure exerted by the roller in real time on the flexible OLED panel, generating corresponding electric signals and generating corresponding position signals according to the generated electric signals; the processing module is used for judging whether the pressure exerted by the roller on the flexible OLED panel is suitable according to the electric signals and the position signals; the adjustment module is electrically connected withthe processing module and adjusts the pressure exerted by the roller on the flexible OLED panel when the pressure exerted by the roller on the flexible OLED panel is not suitable. The embodiments ofthe present invention also disclose a method for attaching a flexible OLED panel to a curved cover plate. With the device and method of the present invention adopted, the number of defects products inan attaching production process can be decreased.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a device and method for bonding a flexible OLED panel to a curved cover. Background technique [0002] Flexible panels are developed on the basis of OLED (Organic Light Emitting Diode, organic light emitting diode) technology. At present, AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode) technology has become the mainstream cutting-edge technology of flexible panels. After Samsung, more and more panel manufacturers are investing in flexible AMOLED technology. Restricted by technical factors, the main application form of flexible panels in the current market is mobile phone terminals with curved edges. Such as Samsung S7Edge, Note 7, VIVO X6 play, etc., are all such applications. The lamination technology of 3D curved cover panels is required in the production of the above products, also known as curved cover panel lamination. Comp...
