The present disclosure relates to the technical field of display, and particularly, to a green light sacrificial layer and a method of manufacturing a touch display device.
With the development of technology, display devices are gradually becoming multifunctional. Touch display devices are one direction of the development. The touch display panel is usually made of a combination of a display panel and a touch module.
At present, in order to reduce a thickness of the overall films of the touch display panel, the touch module is usually manufactured on an external side of the display panel, thereby reducing a transparent substrate and an adhesive layer of the touch module. However, if the touch display panel is manufactured by such a method, and the touch module is manufactured after the display panel is completed, the touch module will undergo a chemical vapor deposition process/physical vapor deposition process/printing and dyeing process, and be exposed to high temperature/vacuum/chemical agent processes, the performance of a frame glue of the display panel will be affected, and the frame glue will easily peel off and dissolve, which may cause a problem of separation between an upper glass and a lower glass of the display panel. If the display panel is assembled and then undergoes a process of manufacturing the touch module, an equipment, such as a vacuum suction washing, curling, etc., in the process of manufacturing the touch module may create local pressures on the display panel, and these pressures will cause problems of damaging a support structure of the display panel or crushing circuits of the support structure, thereby affecting the performance of the touch display panel.
Even if the touch module is manufactured by a dual-sided process of a color filter substrate, followed by assembling the touch module and the display panel to prepare the touch display panel, in a step of removing a scratch-resistant protective layer, the scratch-resistant protective layer is usually removed with a high temperature and high concentration lye since photoresists, such as acrylate and polysiloxane, are usually used as the scratch-resistant protective layer. However, the high temperature and high concentration lye are prone to damage the touch module, thereby causing the failure of a touch function.
The embodiments of the present disclosure provide a green light sacrificial layer and a method for manufacturing a touch display panel, which may enhance the performance of the touch display panel.
