Embodiment 1

[0047] The array substrate provided by Embodiment 1 of the present invention, such as Figure 5 As shown, it includes a base substrate 101, an organic electroluminescent unit 102 located on the base substrate 101, and at least one photoelectric conversion unit 103 corresponding to each organic electroluminescent unit 102, wherein the organic electroluminescent unit The luminescence spectrum of 102 is composed of a first wave band and a second wave band; wherein the first wave band is determined by the emission peak of the luminescence spectrum, and is used to determine the brightness and hue purity of the light emitted by the organic electroluminescent unit;

[0048] The photoelectric conversion unit 103 is specifically used to convert the light of the second wavelength band emitted by the corresponding organic electroluminescent unit 102 and irradiated to the display side (ie, the side of the organic electroluminescent unit 102 away from the substrate 101 ) into electrical ene...

Embodiment 2

[0057]The array substrate provided by Embodiment 2 of the present invention, such as Figure 8 shown. Compared with the array substrate provided by the first embodiment of the present invention, the array substrate provided by the second embodiment of the present invention only has a touch function integrated in the array substrate provided by the second embodiment of the present invention, so the following only provides the second embodiment of the present invention The content of realizing the touch function by the array substrate is introduced, and the overlap with the first embodiment will not be repeated.

[0058] Specifically, in the array substrate provided in Embodiment 2 of the present invention, such as Figure 8 As shown, it also includes: a touch control unit 110 located at the gap between each organic electroluminescent unit 102;

[0059] The touch control unit 110 includes a first touch control electrode 1101, a second insulating layer 1102 and a second touch c...

Embodiment 3

[0062] The array substrate provided by Embodiment 3 of the present invention, such as Figure 9 shown. Compared with the array substrate provided in Embodiment 1 of the present invention, the difference lies in the structure of the photoelectric conversion unit 103 in the two, and the array substrate provided in Embodiment 3 of the present invention can realize thermoelectric and piezoelectric conversion functions. Therefore, only the differences between Embodiment 3 and Embodiment 1 of the present invention will be described below, and repeated descriptions will not be repeated.

[0063] Specifically, in the array substrate provided in Embodiment 3 of the present invention, such as Figure 9 As shown, it also includes: a thermoelectric / piezoelectric conversion unit 111 located between the encapsulation layer 104 and the photoelectric conversion unit 103, the thermoelectric / piezoelectric conversion unit 111 is used to dissipate the thermal energy of the photoelectric conversi...

Abstract

An embodiment of the present invention provides an array substrate and a display panel, including: a base substrate, organic electroluminescent units arranged in an array on the base substrate, and photoelectric conversion units corresponding to each organic electroluminescent unit; The luminescent spectrum of the organic electroluminescent unit is composed of the first band and the second band; the first band is determined by the emission peak of the luminescent spectrum, which is used to determine the brightness and hue purity of the light emitted by the organic electroluminescent unit; photoelectric conversion The unit is at least used for converting the light of the second wavelength band emitted by the corresponding organic electroluminescent unit into electrical energy. Since the photoelectric conversion unit corresponding to the organic electroluminescence unit is added on the array substrate, the light of the second wavelength band emitted by the organic electroluminescence unit and has nothing to do with brightness and color tone purity can be converted into electrical energy by the corresponding photoelectric conversion unit. Electric energy can be used for self-charging, thus improving the utilization rate of self-luminescence of the display panel and saving energy consumption.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] At present, all colors of light in various display panels are formed by mixing red R (red) light, green G (green) light, and blue B (blue) light in different proportions. A group of red sub-pixels, green sub-pixels and blue sub-pixels that can emit red light, green light and blue light constitute a minimum display unit. Any color on the display panel can be recorded and expressed by a set of RGB values, so the red light, green light, and blue light are also called the three primary colors. [0003] The OLED display panel has a unique surface light source self-luminous characteristic. Compared with the LCD display panel that requires a backlight, the OLED display panel has a wider color gamut and a wider viewing angle. Specifically, the wide color gamut of OLED display panels comes from the luminous p...
