Abstract

The invention relates to the technical field of display, in particular to a touch display panel and a touch display apparatus. The touch display panel comprises a first base board with a first substrate and a first conductive film layer arranged on the first substrate, a second base board with a second substrate, a second conductive film layer and a plurality of first spacers, and an electric quantity detection apparatus, wherein each first spacer is arranged on the second substrate and located between the first substrate and the second substrate; a gap is formed between the surface, facing to the first substrate, of each first spacer and the surface, facing to the second substrate, of the first substrate; at least two first spacers in the first spacers are different in height; the second substrate and / or each first spacer is provided with the second conductive film layer; and the first conductive film layer and the second conductive film layer can be electrically connected with the positive electrode and the negative electrode of the electric quantity detection apparatus respectively. According to the technical scheme, the touch display panel can perform a test on pressing force of an external touch medium.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] With the continuous development of touch display technology, in more and more electronic products (such as mobile phones, computers, and televisions), touch display screens have become mainstream. [0003] At present, there are mainly resistive touch and capacitive touch to realize the touch control. Specifically, the resistive touch screen can realize two-point touch through the contact of upper and lower layers of sensing electrodes, but it is difficult to realize multi-point touch. The capacitive touch screen can utilize the mutual capacitance between the emitting electrode and the sensing electrode to realize multi-point touch. However, both the resistive touch display and the capacitive touch display can only detect the touch position, and cannot test the pressing force of the extern...
