Description
Technical Field
The application relates to the technical field of display, in particular to a line identification display device and a line identification method thereof.
Background
At present, optical fingerprint identification becomes one of the most important implementation means of fingerprint identification under a screen. The new optical fingerprint identification technology abandons the traditional optical system of optical fingerprint and uses the light of a display screen as a light source. The optical fingerprint imaging scheme based on the OLED display screen in the prior art has two types, one type is a scheme provided with a light path structure, and the display screen of the scheme mainly comprises three parts: OLED module, optical path structure and Sensor (Sensor) area. The OLED module serves as a light source of the optical fingerprint identification system, the fingerprint is illuminated through self-luminescence, then the return light is collimated, focused and imaged onto the Sensor through the light path structure, the Sensor converts received optical signals into electric signals, and the electric signals are analyzed and compared through the processor chip to verify the fingerprint. Another type of fingerprint imaging scheme discards the optical path structure, which not only reduces the thickness of the whole imaging system, but also reduces the cost of the imaging system. The scheme without the light path structure is that pixels of a certain pattern lightened on an OLED are spliced by utilizing an algorithm after fingers are scanned for multiple times to form a complete fingerprint image. However, because the fingerprint imaging scheme without the optical path structure does not have an optical path structure for collimating and focusing, if a plurality of pattern pixels of the OLED are simultaneously lighted for scanning imaging, as shown in fig. 1, when two adjacent different light sources are relatively close to each other, light reflected to the Sensor has a light mixing region, so that light source crosstalk occurs, and subsequent fingerprint splicing is directly affected. In conclusion, the fingerprint identification device with the prior art without the light path structure is easy to generate the interference when used for fingerprint imaging, and the fingerprint imaging effect is influenced.

Because the colors of any two adjacent color resistors are different in at least one direction of arrangement of the color resistors, for the electroluminescent units which are lighted as the texture recognition imaging light source, even if the adjacent electroluminescent units with different luminous colors are close to each other, light rays which are sent out between the adjacent electroluminescent units with different luminous colors and reflected by textures cannot be received by the same optical sensor, namely, the optical sensor does not have a light mixing area of the adjacent electroluminescent units with different luminous colors, and light source interference does not exist, so that the texture imaging effect can be improved. Furthermore, because the line identification display device provided by the embodiment of the application has no light source interference, the distance between the electroluminescent units as the line identification imaging light source can be shortened, the line imaging efficiency can be improved, and the line identification efficiency can be improved.
It should be noted that, when the texture recognition display device provided in the embodiment of the present application performs texture imaging, at least part of the electroluminescent units need to be lit as a texture recognition imaging light source, for example, part of the electroluminescent units may be lit as a point light source, and part of the electroluminescent units may also be lit as a line light source, that is, imaging may be performed by using the point light source, and imaging may also be performed by using the line light source.
Optionally, the light emitting colors of any two adjacent electroluminescent units as the texture recognition imaging light sources are different, and the colors of any two adjacent color resists are different.
When the texture imaging is carried out, the pixel units serving as texture identification imaging light sources are lightened, the light emitting colors of any two adjacent electroluminescent units serving as the texture identification imaging light sources are different, namely the lightened pixel units serve as point light sources, and the texture identification adopts a point light source imaging mode.
For the point light source imaging mode, correspondingly, taking a color resistor array including two colors as an example, the arrangement mode of the color resistors is as shown in fig. 3, the color resistors 5 in the color resistor array are arranged along a first direction X and a second direction Y, the color resistor array includes a red color resistor 6 and a blue color resistor 7, and any two adjacent color resistors 5 have different colors, that is, any two adjacent color resistors 5 along the first direction X have different colors, and any two adjacent color resistors 5 along the second direction Y have different colors.
Therefore, the electroluminescent units with different emergent colors corresponding to the colors of the color resistors are lightened, the emergent light of the electroluminescent units with different lightened adjacent emergent colors can be received by the optical sensor only through the color resistors with the corresponding colors after being reflected by the lines due to the different colors of any two adjacent color resistors, the optical sensor does not have a light mixing area of the electroluminescent units with two lightened adjacent different emergent colors, the light source interference does not exist, and the line imaging effect can be improved.
Optionally, in the first direction, the light emitting colors of any two adjacent electroluminescent units serving as the texture recognition imaging light source are the same, and the colors of any two adjacent color resistors are the same; or, in the second direction, the light emitting colors of any two adjacent groups of the electroluminescent units as the line identification imaging light sources are the same, and the colors of any two adjacent color resistors are the same.
When the line imaging is carried out, the pixel unit serving as the line identification imaging light source is lightened. For example, in the first direction, the light emitting colors of any two adjacent electroluminescent units as the texture recognition imaging light sources are the same, that is, the lighted pixel units are used as line light sources, the extending direction of the line light sources is the first direction, and the texture recognition adopts a line light source imaging mode. Correspondingly, taking a color resistor array including two colors as an example, the color resistor array is shown in fig. 4, the color resistors 5 in the color resistor array are arranged along a first direction X and a second direction Y, the color resistor array includes a red color resistor 6 and a blue color resistor 7, any two adjacent color resistors 5 along the first direction X have different colors, and any two adjacent color resistors 5 along the second direction Y have the same color.
For the line light source imaging mode, the colors of any two adjacent color resistors are the same along one of the arrangement directions of the color resistors, so that the light emitted by the lighted electroluminescent units with different adjacent emergent colors can be ensured, after being reflected by lines, the light can be received by the optical sensor only through the color resistors with corresponding colors, the optical sensor does not have the light mixing areas of the electroluminescent units with different luminous colors as the line identification imaging light source, the light source interference does not exist, and the line imaging effect can be improved. Certainly, in the second direction, the light emitting colors of any two adjacent electroluminescent units serving as the texture recognition imaging light sources are the same, that is, the lighted pixel units serve as the line light sources, the extending direction of the line light sources is the second direction, the texture recognition adopts a line light source imaging mode, and the arrangement mode of the corresponding color resistors is as follows: any two adjacent color resists in the second direction have the same color. The arrangement of the color resistors can be selected according to the arrangement mode of the lighted line light sources.
Optionally, in the texture recognition display device shown in fig. 2 provided in this embodiment of the present application, the color resistance array includes color resistances of two colors.

As shown in fig. 2, the light emitted from the red electroluminescent unit R is reflected by the grain 13 to the grain recognition module, and can only reach the optical sensor 4 through the red color resistor 6. The light emitted by the blue light electroluminescent unit B is reflected by the grain 13 to the grain identification module and can only reach the optical sensor 4 through the blue color resistor 7. The texture 13 may be a finger or palm texture. Therefore, light rays which are emitted between the adjacent electroluminescent units with different luminous colors and reflected by the lines and are used as the line identification imaging light source cannot be received by the same optical sensor, namely, the optical sensor does not have a light mixing area of the electroluminescent units with two adjacent different luminous colors and lightened as the line identification imaging light source, and light source interference does not exist, so that the line imaging effect can be improved.
Optionally, a plurality of the electroluminescent units comprises: a red light electroluminescent unit, a blue light electroluminescent unit, and a green light electroluminescent unit; the color resistors comprise a blue color resistor and a green color resistor.
Of course, the color resistor array may also include color resistors of three colors. Alternatively, as shown in fig. 5, a plurality of the electroluminescent units include: a red light electroluminescent unit R, a blue light electroluminescent unit B, and a green light electroluminescent unit G; the color resistors 4 include a red resistor 6, a blue resistor 7 and a green resistor 14.
When the color resistor array includes color resistors of three colors, as for the point light source imaging method, the arrangement of the color resistors may be as shown in fig. 6, the color resistors 5 in the color resistor array are arranged along a first direction X and a second direction Y, the color resistor array includes a red color resistor 6, a blue color resistor 7 and a green color resistor 14, and any two adjacent color resistors 5 have different colors, that is, any two adjacent color resistors 5 along the first direction X have different colors, and any two adjacent color resistors 5 along the second direction Y have different colors.
When the color resistor array includes color resistors of three colors, as for a line light source imaging mode, the arrangement of the color resistors may be as shown in fig. 7, the color resistors 5 in the color resistor array are arranged along a first direction X and a second direction Y, the color resistor array includes a red color resistor 6, a blue color resistor 7 and a green color resistor 14, any two adjacent color resistors 5 along the first direction X have different colors, and any two adjacent color resistors 5 along the second direction Y have the same color. Of course, for the line light source imaging mode, the arrangement of the color resistors may be that the colors of any two adjacent color resistors along the first direction are different, and the colors of any two adjacent color resistors along the second direction are the same.
Optionally, in the texture recognition display device provided in the embodiment of the present application, in the electroluminescent unit having the same light emitting color as the color resistance color, the light emitting spectra of the electroluminescent units of different types do not overlap.
No matter how many kinds of color resists the color resist array includes, in the electroluminescent unit that the light-emitting color is the same with the color resist color, the luminous spectrum of different electroluminescent units is not overlapped, thus the optical sensor can only receive the light that the electroluminescent unit that corresponds to the color resist color sent out. Even if the adjacent electroluminescent units with different luminous colors as the texture recognition imaging light source are close to each other, light rays which are emitted between the adjacent electroluminescent units with different luminous colors as the texture recognition imaging light source and reflected by the textures cannot be received by the same optical sensor, namely, the optical sensor does not have a light mixing area of the adjacent electroluminescent units with different luminous colors as the texture recognition imaging light source, and light source interference does not exist, so that the texture imaging effect can be improved.
Taking the electroluminescent cell comprising R, G, B as an example, when the color resistor array comprises only two colors of color resistors, the colors of the color resistors are red and blue because the spectrums of red light and blue light emitted by the electroluminescent cell do not overlap, so that the optical sensor can be ensured to only receive the light emitted by the electroluminescent cell corresponding to the color of the color resistor. Of course, the light emitting material of the electroluminescent unit is selected so that the electroluminescent unit emits light with high purity, and under the condition that the light emitting spectra of the electroluminescent unit do not overlap, other color resistance combination modes can be selected, for example, the colors of the color resistance are blue and green. Certainly, under the condition that the spectrums of the red light, the blue light and the filtered light emitted by the electroluminescent unit are not overlapped, the color resistance array comprises a red color resistance, a blue color resistance and a green color resistance, and the grain imaging efficiency can be further improved.
Optionally, in the texture recognition display device shown in fig. 2 and 5 provided in this embodiment of the present application, the texture recognition module 1 further includes a black matrix 9 located between the color resists 5.

Because the colors of any two adjacent color resistors are different in at least one direction of arrangement of the color resistors, for the electroluminescent units which are lighted as the texture recognition imaging light source, even if the adjacent electroluminescent units with different luminous colors are close to each other, light rays which are sent out between the adjacent electroluminescent units with different luminous colors and reflected by textures cannot be received by the same optical sensor, namely, the optical sensor does not have a light mixing area of the adjacent electroluminescent units with different luminous colors, and light source interference does not exist, so that the texture imaging effect can be improved.

Because the colors of any two adjacent color resistors are different in at least one direction of arrangement of the color resistors, for the electroluminescent units which are lighted as the texture recognition imaging light source, even if the adjacent electroluminescent units with different luminous colors are close to each other, light rays which are sent out between the adjacent electroluminescent units with different luminous colors and reflected by textures cannot be received by the same optical sensor, namely, the optical sensor does not have a light mixing area of the two adjacent electroluminescent units with different luminous colors as the texture recognition imaging light source, and light source interference does not exist, so that the texture imaging effect can be improved.
