Problems solved by technology

Non-black inks or photoresist materials have ideal light-shielding properties only when they are designed with sufficient thickness. Therefore, when using non-black inks or photoresist materials to form a frame, the thickness is too thick, which often makes the production of transmission lines difficult. , and the transmission line may thus be prone to disconnection problems

Embodiment Construction

[0039] Please also refer to Figure 1A , Figure 1B and figure 2 , the touch panel 100 has an active area 102 and a peripheral area 104 surrounding the active area 102 . Generally speaking, the active area 102 can have light-transmitting characteristics, so that after the touch panel 100 is assembled on the display panel 400 to form a touch display panel, the user can operate in the active area 102 and watch the screen through the active area 102, The display panel 400 may be a liquid crystal display panel, an organic light emitting display panel, an electrowetting display panel, an electrophoretic display or other flat display panels.

[0040] At this time, in order to realize the function of touch sensing, the touch panel 100 includes a touch sensing component 110 disposed on the cover plate 160 , and the touch sensing component 110 is disposed in the active area 102 . In addition, the peripheral component 106 formed by the transmission line 120 and the like can also be d...

Abstract

The invention discloses a touch panel and a touch display panel. The touch panel is provided with an active area and a peripheral area around the active area and comprises a cover plate, a touch sensing component, a non-black layer, a plurality of transmission circuits and a protective layer. The touch sensing component is disposed on the cover plate and located in the active area. The non-black layer is disposed on the cover plate and located in the peripheral layer. The transmission circuits are disposed on one side of the non-black layer, which is far away from the cover plate. The transmission circuits located in the peripheral area are electrically connected to the touch sensing component. A reflecting pattern layer is disposed on one side of the non-black layer, which is far away from the cover plate and is located in the peripheral area. The reflecting pattern layer is at least located in the area of the peripheral area, which is not covered by the transmission circuits. The protective layer is disposed on one side of the transmission circuits, which is far away from the cover plate. Sufficient shading can be achieved without increasing thickness of the non-black layer of the touch panel.

Description

technical field [0001] The present invention relates to a touch panel and a touch display panel, and in particular to a touch panel and a touch display panel whose frame color is not black. Background technique [0002] The touch display device is composed of a display panel and a touch panel disposed on the display panel. Among them, in order to transmit these signals, the touch panel has a plurality of transmission lines arranged in the peripheral area of ​​the touch panel, and in order to cover the transmission lines, a black ink layer is often arranged at the position corresponding to the peripheral area of ​​the touch display device to cover These transmission lines form a black frame in the touch display device. [0003] For the user, the black frame does not necessarily meet the user's demand for appearance. Non-black inks or photoresist materials have ideal light-shielding properties only when they are designed with sufficient thickness. Therefore, when using non-b...
