Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] A touch display screen with fingerprint recognition, such as figure 1 As shown, an upper glass substrate 82 , a second driving circuit layer 32 , a first driving circuit layer 20 , a lower glass substrate 2 and a lower polarizing layer 21 are sequentially arranged from top to bottom. Wherein, the first driving circuit layer 20 and the lower polarizing layer 21 are respectively disposed on the top and bottom of the lower glass substrate 2 , and the second driving circuit layer 32 is disposed on the bottom of the upper glass substrate 82 . The upper glass substrate 82 and the lower glass subs...

Abstract

The invention relates to a touch control display screen with fingerprint identification and a manufacturing method thereof. The touch control display screen comprises two glass substrates, a lower glass substrate is equipped with a TFT film switch and an upper glass substrate is equipped with a color filter. The upper glass substrate of the display screen is firstly made into the shape required for the terminal, By the enhancement and the ink printing, and then the circuits required for touch control, display and fingerprint identification, color filters, polarizing materials and liquid crystal alignment layers are coated on the glass. At last, the upper and low glass substrates are laminated and filled with liquid crystal to form a touch display screen module. The conductive particles inthe adhesive frame are used to conduct the inductive wire and the display driving wire of the touch control of the two glass substrates, and the conductive particles are led to the upper glass substrate, and the FPC and the wire are bound and connected with an ACF. The invention integrates the fingerprint identification function, the touch control function and the display function, reduces the product attaching assembly process, integrates the fingerprint with the touch display module, and shortens the border of the lower edge of the product.

Description

technical field [0001] The invention relates to a touch display screen with fingerprint identification and a manufacturing method thereof, belonging to the technical field of displays. Background technique [0002] At present, there are mainly several types of touch displays in terms of design principles: the first type is to install a touch screen on the display, so that the display becomes a display with a touch function. This kind of touch display screen is composed of two parts: the display screen and the touch screen. The two parts are bonded together with double-sided adhesive, foam or transparent adhesive, so that from the user's point of view, it is the same as the display screen. Touch on the top to achieve touch display integration. The second is to integrate a touch sensor on the display, such as the touch display of IPHONE5S. This touch function is to make the sensing electrode of the capacitor inside or on the surface of the display, and then cover the glass co...
