Improve the recognition effect of living things feature recognition.
It should be understood that the living things feature recognition mould group 220 received is used to carry out biological characteristic in the embodiment of the present application
The optical signal of identification can be the light of the carry out optical treatment for the optical signal that human finger 210 issues the external light source 230
Signal.It is transmitted for example, the optical signal that the living things feature recognition mould group 220 receives can be progress via human finger 210
The optical signal of the backlight module 213 is passed through afterwards.The embodiment of the present application is not specifically limited in this embodiment.
As shown in figure 3, the electronic equipment 200 can also include the connection circuit being connected with the external light source 230
231, the connection circuit 231 for receiving control signal, the control signal for control the external power supply 230 it is luminous or
Person does not shine.For example, the connection circuit 231 can be circuit board.For example, printed circuit board (Printed Circuit
Board, PCB) or flexible circuit board (Flexible Printed Circuit, FPC).
As one embodiment, the backlight module 213 from top to bottom successively may include composite membrane, bright enhancement film, diffusion
Film and light guide plate (light guide plate).In image display process, it is seen that the visible light that light source issues passes through light guide plate
It is transmitted to diffusion barrier later, the light after the diffusion membrane diffusion is transmitted to the bright enhancement film, and the bright enhancement film is for increasing
The optical signal that benefit receives, and the optical signal after gain is sent to composite membrane, the composite membrane is used for further gain receiver
The optical signal arrived, and by the optical signal transmission after gain to display screen, for performing image display.Further, the backlight
Mould group 213 can also include steel plate and/or reflectance coating, and the reflectance coating can be set in the lower section of the light guide plate, and being used for will
Visible light source returns the light guide plate towards the visible reflectance that the direction opposite with display module 212 is projected, and then can described in raising
The utilization rate for the light that light-exposed source is projected, light court and 212 phase of display module that the steel plate is used to that the visible light source to be stopped to project
It projects in anti-direction.
