It is understood that the pixel unit 111 includes red pixels, green pixels, and blue pixels. The color combination of the three pixel points can form better chromaticity for the display screen 1, so that the display screen 1 can be watched by human eyes conveniently.
Referring to fig. 2, the plurality of spare pixels 112 are respectively disposed in the plurality of gaps so as not to interfere with the light emission of the pixel unit 111 and affect the display of the display panel 1. It will be appreciated that the spare pixels 112 are green pixels. The green light source can further protect the eyes of the user, further improving the reliability of the mobile terminal 100. Of course, in other embodiments, the spare pixels 112 may also be red pixels or blue pixels.
In this embodiment, referring to fig. 3, the fingerprint identification module 2 is disposed on the display screen 1, so that the mobile terminal 100 has a fingerprint identification function. Specifically, the one side that fingerprint identification module 2 is close to display screen 1 is fingerprint contact surface 21a to in the user carries out the fingerprint at display screen 1 and presses.
It can be understood, fingerprint identification module 2 is including the prism 21 that encapsulates together, image sensor 22 and fingerprint controller 23, prism 21 is close to the setting of display screen 1, and prism 21 is close to the one side of display screen 1 and is fingerprint contact surface 21a, the light that standby pixel 112 sent shines to pressing on the fingerprint contact surface 21a of waiting to discern fingerprint 20 and with waiting to discern fingerprint 20 and take place the total reflection, the light of total reflection is incident to image sensor 22 through prism 21, image sensor 22 acquires the fingerprint image according to the light of total reflection, the fingerprint image that fingerprint controller 23 discernment image sensor 22 sent.
Specifically, prism 21, image sensor 22 and fingerprint controller 23 in the fingerprint identification module 2 are because the encapsulation is together, so the whole blocky that is of fingerprint identification module 2. The prism 21, the image sensor 22, and the fingerprint controller 23 are plastic-packaged together by EMC (epoxy molding compound). Wherein, the encapsulation technology of fingerprint module can not influence the normal work of optical devices such as prism 21.
The user can perform fingerprint recognition by pressing a fingerprint against the fingerprint contact surface 21a of the prism 21. Image sensor 22 and fingerprint controller 23 are located the below of prism 21, and image sensor 22 and fingerprint controller 23 keep away from the fingerprint contact surface 21a of fingerprint module promptly to image sensor 22 acquires the light of reflection to on the prism 21, thereby converts light signal into electrical signal transmission and handles for fingerprint controller 23.
In this embodiment, referring to fig. 3, the sensor 3 is electrically connected to the display 1, so that the spare pixel 112 emits light when the fingerprint 20 to be identified approaches the fingerprint contact surface 21 a. It will be appreciated that the sensing member 3 is a proximity sensor. The proximity sensor is close to the prism 21 and is arranged and electrically connected with the display screen 1, when a user presses the fingerprint 20 to be recognized on the display screen 1 just opposite to the fingerprint contact surface 21a or directly on the fingerprint contact surface 21a, the sensing piece 3 senses a signal, the plurality of standby pixels 112 of the display screen 1 emit light and the fingerprint 20 to be recognized are totally reflected, the totally reflected light is incident to the image sensor 22 through the prism 21, the image sensor 22 acquires a fingerprint image according to the totally reflected light, and the fingerprint controller 23 recognizes the fingerprint image sent by the image sensor 22. After the user's fingerprint 20 to be recognized leaves, the sensing member 3 does not sense a signal, and the plurality of spare pixels 112 of the display panel 1 stop emitting light. Through add a plurality of stand-by pixels 112 on the display structure at display screen 1 and through the contact start stand-by pixel 112 that the response of response piece 3 waited to discern fingerprint 20 come as discernment fingerprint light for the required light source of fingerprint identification module 2 during operation need not to use the light of pixel unit 111, influences the life-span of display screen 1.
