Abstract
The invention discloses a touch display panel. The touch display panel comprises a colored filtering substrate, an active matrix transistor substrate, a liquid crystal layer, an electrode pair, a plurality of touch sensing units and at least one anti-interference patch. The active matrix transistor substrate and the colored filtering substrate are correspondingly arranged. The liquid crystal layer is arranged between the colored filtering substrate and the active matrix transistor substrate. The electrode pair is arranged on the active matrix transistor substrate and comprises a pixel electrode and a common electrode. An edge electric field is generated between the pixel electrode and the common electrode to control liquid crystal molecules of the liquid crystal layer to rotate. The touch sensing units are arranged on the colored filtering substrate in a coplanar mode. Gap regions are formed between the adjacent touch sensing units, and the anti-interference patches are arranged in the gap regions. The multiple touch sensing units and the anti-interference patches form a conductive structure through laser tempering. The touch display panel has accurate transferring patterns; meanwhile, the problems that when fed into a roaster to be tempered, the substrates are prone to bending, damage or pollution and the like are solved, and manufacturing cost is low.
Description
【Technical field】 [0001] The present invention relates to a touch display panel, in particular to a touch display panel manufactured through a laser patterning process. 【Background technique】 [0002] In recent years, touch technology has gradually been widely used in general consumer electronics products, such as mobile communication devices, digital cameras, digital music players (MP3), personal digital assistants (PDA), satellite navigation devices (GPS), Hand-held PC (hand-held PC), tablet computer (tablet), and even a new super mobile computer (Ultra MobilePC, UMPC) and so on. Touch technology can be applied to the display panel in various forms, such as adding a touch panel on the display panel (plug-in type), or making a touch sensing unit directly on the display panel (embedded type, also divided into on -cell and in-cell). [0003] However, the process of making the touch sensing unit needs to be formed through film formation, exposure, development, etching and ot...
