Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Each of the following switching transistors may be a transistor, each transistor may be a thin film transistor or a field effect transistor or other devices having the same characteristics, and may be an N-type transistor or a P-type transistor, and different types of transistors are adopted mainly considering the conduction form thereof, and the N-type transistor is conducted at a low level, and the P-type transistor is conducted at a high level. To distinguish the two poles of the transistor, except for the control pole, one pole is called a first pole, and the other pole is called a second pole. The control electrode is a grid electrode, the first electrode can be a drain electrode, and the second electrode can be a source electrode; alternatively, the control electrode is a gate, the first electrode may be a source, and the second electrode may be a drain.
As shown in fig. 1, a display panel according to an embodiment of the present invention includes a light emitting layer, two opposite light emitting directions are formed on two sides of the light emitting layer, and a light guiding layer 6 and a sensing layer 5 are sequentially stacked along the light emitting direction in one of the light emitting directions; the light guide layer 6 is used for emitting light emitted from the light emitting layer to the light guide layer 6 to the sensing layer 5 at a preset angle; the sensor layer 5 includes a plurality of first light-transmitting regions each provided with the photosensitive element 22, and a first light-shielding region 26 surrounding each of the first light-transmitting regions.
For convenience of description, the light emitting layer is defined as having one light emitting direction as a front side and the other light emitting direction as a back side, the front side is used for displaying images, the back side provides a light source required for fingerprint identification, and the light source required for fingerprint identification is provided through the back side, so that waste of light energy can be reduced. The light guide layer 6 and the sensing layer 5 are both arranged on the back of the display panel. Accordingly, the front surface of the light emitting layer also corresponds to the front surface of the display panel, and the back surface of the light emitting layer also corresponds to the back surface of the display panel.
When fingerprint identification is carried out, a finger 1 is pressed on the back of the display panel, light in the back light outgoing direction passes through the light guide layer 6, then is emitted to the sensing layer 5 at a preset angle, passes through the first light transmission area of the sensing layer 5 and irradiates the finger 1 of a user, the fingerprint valley position 31 of the finger 1, light enters the light thinning medium from the optical density medium, when the incident angle of the light thinning medium is larger than the critical angle, total reflection occurs, and more light is reflected into the photosensitive element 22, so that the light intensity is high, and the current generated by the photosensitive element 22 is large; in the fingerprint ridge position 30 of the finger 1, the refractive index difference of the medium on the propagation path of the light is small, refraction and diffuse reflection occur, and the light reflected into the photosensitive element 22 is small, so that the light intensity is low, and the current generated by the photosensitive element 22 is small. The photosensitive element 22 performs fingerprint recognition based on small changes in current points generated by the intensity of the reflected light at the fingerprint valley and ridge locations 30.
Above-mentioned scheme, the luminescent layer has two light-emitting directions that carry on the back mutually, and one of them light-emitting direction is as the display surface, and another light-emitting direction is as fingerprint identification's light source, when carrying out fingerprint identification, need not to carry out the brightening to local area and shows, consequently can not aggravate the ageing of specific area, does not have the uneven problem of luminance because of local ageing causes. In addition, fingerprint identification and picture display are separately arranged on the upper side and the lower side of the display panel, so that adverse effects on display cannot be caused.
As an implementation manner, in order to prevent the problem that the display is abnormal due to a large amount of ambient light on the back surface passing through the light emitting layer during the fingerprint identification, for example, if the ambient light on the back surface passing through the light emitting layer is too strong, it may affect the brightness of the normal display screen, so that the user cannot clearly view the display screen, in order to solve the problem, the first electrochromic layer 8 is further included, and the first electrochromic layer 8 is located between the light emitting layer and the light guiding layer 6; the first electrochromic layer 8 is used to block a predetermined amount of ambient light from being transmitted to the light emitting layer when the photosensitive element 22 is operated.
For example, but not limited to, when the photosensitive element 22 is in operation, that is, when fingerprint recognition is performed, a certain voltage is applied to the first electrochromic layer 8, so that the first electrochromic layer 8 is in a semi-transparent state, and the semi-transparent state is changed by changing the magnitude of the voltage, and the semi-transparent state may be, for example, 40%, 45%, 50%, 55% of back ambient light is transmitted, and a corresponding amount of ambient light is blocked, so as to reduce interference of the back ambient light on front display. In general, the higher the voltage applied to the first electrochromic layer 8, the higher the transmittance of light thereof.
Examples of the electrochromic material used for the first electrochromic layer 8 include, but are not limited to, polyaniline, viologen, tungsten oxide, and the like.
As an implementation manner, a diffusion sheet 7 is arranged between the first electrochromic layer 8 and the light guide layer 6, light emitted from the back light-emitting direction can be uniformly mixed through the diffusion sheet 7, so that the uniformly mixed light enters the light guide layer 6, and the difference of fingerprint identification sensitivity caused by different brightness of light in different areas is avoided.
As an implementation manner, a side of the sensing layer 5 facing away from the light emitting layer is provided with a second electrochromic layer 4; the second electrochromic layer 4 is intended to be in a transparent state when the photosensitive element 22 is in operation, i.e. when fingerprint recognition is performed. When fingerprint identification is carried out, the second electrochromic layer 4 is in a transparent state, and light emitted by the light guide layer 6 can smoothly reach the finger 1. After fingerprint identification is finished, the second electrochromic layer 4 can be in a light-blocking state, so that ambient light on the back cannot enter the light-emitting layer, and the situation that the ambient light on the back interferes with display is thoroughly avoided.
The electrochromic material used for the second electrochromic layer 4 is, for example, but not limited to, polyaniline, viologen, tungsten oxide, and the like.

By providing the light-shielding layer 10 so that the light-emitting elements 16 are disposed in the opening regions of the light-shielding layer 10, crosstalk between adjacent light-emitting elements 16 is prevented from occurring, which affects the display effect.
