BACKGROUND
Organic Light-Emitting Diode (OLED) is a display lighting technology gradually developed in recent years. Especially in the display industry, it is one of the hot spots in the research field of flat panel display. Compared with Liquid Crystal Display (LCD), it has the advantages of high response, high contrast, low working voltage, thin and light, flexibility, low energy consumption, low production cost, self-luminescence, wide viewing angle and fast response speed.
Fingerprint is unique to everyone. With the development of the market, fingerprint identification technology has become one of the important functions of electronic products. This function has been concerned by many electronic manufacturers and applied in their electronic products, such as mobile phones, tablet computers and smart wearable devices. In this way, before operating the electronic device with fingerprint identification function, the user only needs to touch the fingerprint identification module of the electronic device with his finger to verify the authority, thus simplifying the authority verification process.
When the fingerprint identification structure is located in the display panel, and the position of the fingerprint identification structure coincides with the light emitting region of a pixel unit, the fingerprint identification structure will affect the light emitting of the pixel unit and the display effect of the display panel.

FIG. 1 is a first top view of a display panel according to an implementation of the present disclosure. FIG. 2 is a first sectional view of a display panel according to an implementation of the present disclosure. As shown in FIGS. 1 and 2, an implementation of the present disclosure provides a display panel, including a display region, the display region includes at least one functional unit 100 disposed on a substrate 40, the one functional unit 100 includes a pixel unit 10 and at least one non-display unit 20, wherein the pixel unit 10 includes at least one sub-pixel, and the orthographic projection of the pixel unit 10 on the substrate 40 does not overlap the orthographic projection of the at least one non-display unit 20 on the substrate 40.
In an exemplary implementation, the non-display unit 20 does not have a light emitting function. The non-display unit 20 may include at least one of a fingerprint identification unit, an iris identification unit, a detection unit and a sensor.
In an exemplary implementation, a pixel unit may include at least one Green (abbreviated as G) sub-pixel, at least one Blue (abbreviated as B) sub-pixel, and at least one Red (abbreviated as R) sub-pixel. A green sub-pixel, a blue sub-pixel, and a red sub-pixel of a pixel unit emit green light, blue light, and red light, respectively, thereby causing the display panel to display a picture.
The display panel of the implementation of the present disclosure arranges the non-display unit 20 in the display region, and makes the non-display unit 20 not block the pixel unit, so that the display panel of the implementation of the present disclosure can have other functions besides the light emitting function, such as a fingerprint identification function, through the non-display unit 20. The non-display unit 20 does not occupy the region of the pixel unit and does not affect the emission of sub-pixels such as the green sub-pixel 1, the blue sub-pixel 2, and the red sub-pixel 3, thereby preventing the non-display unit 20 from affecting the display effect of the display panel. Take the non-display unit 20 as the fingerprint identification unit as an example. When the display panel is in the fingerprint identification state, the non-display unit 20 can recognize the intensity of light reflected by a finger, thereby recognizing a fingerprint.
In an exemplary implementation, the pixel unit in the display panel of the implementation of the present disclosure may be an Organic Light-Emitting Diode (OLED for short), it can also be Light-Emitting Diode (LED for short) or Micro LED, and it can also be other types of light emitting devices or light transmitting devices (such as color film). Among the various types of pixel units mentioned above, organic light-emitting diodes have smaller volume, low working voltage, thinness, flexibility, low energy consumption, low production cost, self-luminescence and the like.
In an exemplary implementation, the non-display unit 20 in the display panel of the implementation of the present disclosure may be a fingerprint identification unit. The fingerprint identification unit can be a capacitive fingerprint identification unit, an optical PIN, and an Organic Photo Diode (OPD). Among the various types of the fingerprint identification unit, the organic photodiode has high light responsiveness, can achieve high-pixel full-screen fingerprint identification, has narrow response wavelength, and is not easily affected by ambient light.
Take the non-display unit 20 as the fingerprint identification unit as an example. As shown in FIGS. 1 and 2, one functional unit 100 includes one pixel unit 10 and one non-display unit 20 which may employ an organic photodiode. One pixel unit 10 includes one green sub-pixel 1, one blue sub-pixel 2, and one red sub-pixel 3. The orthographic projection of the pixel unit 10 on the substrate does not overlap the orthographic projection of at least one non-display unit 20 on the substrate. When the display panel of the implementation of the invention carries out fingerprint identification, at least one of the green sub-pixel 1, the blue sub-pixel 2, and the red sub-pixel 3 of the pixel unit 10 emits light emitted in the finger direction. Light is emitted to fingerprints, reflected by the fingerprint to form reflected light emitted toward the non-display unit 20, the non-display unit 20 detects the light reflected by the fingerprint, and the height fluctuation of the fingerprint will have reflected light with different intensities, so that different fingerprint appearances will be distinguished by the non-display unit 20, thereby achieving the fingerprint identification operation in the display region of the display panel.
In an exemplary implementation, the material of the substrate includes glass, plastic, or flexible substrate material. The flexible substrate material includes one or more of polyimide (PI), polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), Polyallylate, polycarbonate (PC), cellulose triacetate (TAC), cellulose acetate propionate (CAP) or Acrylamide. Because polyimide is one of the organic polymer materials with the best comprehensive performance, the flexible material has good optical, chemical resistance, water and oxygen resistance and other properties, therefore, the material of the substrate in the display panel of this implementation can adopt polyimide.
