[0032] The manufacturing method of the above-mentioned touch display device includes: coating and forming a high-resistance layer on the color filter substrate of the thin film transistor display module.
[0033] Preferably, when coating the color filter substrate of the thin film transistor display module to form the high resistance layer, the slurry is coated on the color filter substrate and baked to form the high resistance layer, wherein The slurry comprises 10%-12% of graphene, 35-45% of water, 20-30% of surfactant and 23-35% of cross-linking agent in terms of mass percentage. Further preferably, the surfactant is polyethylene glycol-400, and the crosslinking agent is dicumyl peroxide. Preferably, when coating and forming a high-resistance layer on the color filter substrate of the thin film transistor display module, the slurry is coated on the color filter substrate by a rotary scraping method, and after air-drying for 3 to 5 minutes, Bake at 100° C. to 120° C. for 28...
Embodiment 1
[0041] The preparation of the high resistance layer of the touch display device of Example 1 comprises the following steps:
[0042] (1) Use a cleaning machine to clean the TFT substrate of the TFT module with pure water, lye, BJ spray, DI spray, and high-pressure spray in sequence, clean the dirt and dust on the surface of the substrate, and dry it with cold air and hot air. Static electricity dissipates, check that the surface is free of dirt and dust, and wait for coating.
[0043] (2) The substrate is placed on the working surface of the automatic knife scraping and rotary scraping machine by the manipulator, and then through automatic positioning and centrifugal law, a thin layer of slurry is automatically scraped to prepare a high-resistance layer. The rotary scraping speed is adjustable at 1500rpm , the rotary scraping time is 10 seconds, the uniformity is controlled within ± 3%, and it is naturally air-dried for 5 minutes in the working environment, and then sent to a du...
