Problems solved by technology
[0002] As the main components to realize human-computer interaction, the control chip (IC, Integrated Circuit) and FPC (Flexible Printed Circuit, flexible circuit board) of the current mainstream touch screen are usually integrated, which is obviously not convenient for subsequent assembly and maintenance.
Moreover, in the existing design, the control chip is pasted on the FPC and attached to the back of the touch screen through the FPC. Therefore, the touch screen needs to avoid the structure of the control chip, which is easy to reduce the structure of the touch screen. Intensity, thus increasing the risk of bad display phenomena such as screen cracking and white marks

Embodiment Construction
[0023] The main purpose of the present invention is to arrange the control chip of the touch display screen on an adapter board instead of the FPC, separate the control chip and the FPC, and when the FPC is attached to the back of the touch display screen, the touch screen and The shell of the terminal does not need to avoid the structure of the control chip, thereby reducing the risk of bad display phenomena such as screen cracks and white marks, and the adapter board is detachably connected to the touch display screen, which is convenient for assembly and maintenance.
[0024] Wherein, the terminal applicable to the present invention can be a portable electronic device such as a smart phone, a PDA (Personal Digital Assistant, personal digital assistant or a tablet computer), or a wearable device worn on the body or embedded in clothing, jewelry, or accessories. , and can also be other intelligent electronic devices with a touch screen and touch functions.

The invention discloses a touch display screen and a touch control terminal. An adapter board (Flexible Printed Circuit, FPC) is designed on the touch display screen. A control chip is arranged on one board surface of the adapter board. A first elastic piece and a second elastic piece connected with the control chip are arranged on an opposite board surface of the adapter board. The adapter board and a touch screen and a display screen are oppositely fixed by adopting a removable manner. The first elastic piece is in contact with a first contact point in fixing, the second elastic piece is in contact with a second contact point, and the control chip establishes control connection relationships with the touch screen and the display screen. On the basis thereof, the control chip and the FPC can be separately arranged in the terminal, assembly and maintenance are facilitated, and appearance risks of bad display phenomena such as screen cracking and white marks are reduced.
Description
technical field [0001] The invention relates to the field of touch display, in particular to a touch display screen and a touch terminal. Background technique [0002] As the main components to realize human-computer interaction, the control chip (IC, Integrated Circuit) and FPC (Flexible Printed Circuit, flexible circuit board) of the current mainstream touch display are usually integrated, which is obviously inconvenient for subsequent assembly and maintenance. Moreover, in the existing design, the control chip is pasted on the FPC and attached to the back of the touch screen through the FPC. Therefore, the touch screen needs to avoid the structure of the control chip, which is easy to reduce the structure of the touch screen. Intensity, thereby increasing the risk of bad display phenomena such as screen cracking and white marks. Contents of the invention [0003] In view of this, the present invention provides a touch display screen and a touch terminal, which can sepa...
