Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of OLED light sources, specifically relating to a high-brightness OLED red light source. Background Technology
[0002] OLED stands for Organic Light Emitting Diode, which is an organic light-emitting display technology. Its principle involves sandwiching an organic light-emitting layer between two electrodes. When electrons from the positive and negative electrodes meet in this organic material, light is emitted. Its component structure is simpler than the currently popular TFT-LCD, and its production cost is only about 30-40% of that of TFT-LCD. Besides its lower production cost, OLED has many other advantages, such as its self-emissive nature. Currently, LCDs require backlight modules (adding lamps behind the liquid crystal), but OLED emits light itself when powered, saving the weight, size, and power consumption of lamps (lamp power consumption accounts for almost half of the entire LCD screen). This allows for products with a thickness of only about two centimeters, a lower operating voltage of 2 to 10 volts, and superior response time (less than 10ms) and color reproduction compared to TFT-LCD. Furthermore, its flexibility makes it suitable for a wide range of applications.
[0003] During the OLED light emission process, low brightness can easily lead to poor luminous efficiency and unstable performance. Utility Model Content
[0004] The purpose of this invention is to provide a high-brightness OLED red light source to solve the technical problem that the low brightness of OLED light emission can easily lead to poor light efficiency and unstable effect, thereby achieving stable light brightness and improving light efficiency.
[0005] To address the aforementioned technical problems, this utility model provides a high-brightness OLED red light source, comprising:
[0006] OLED red light source body and prism surface layer;
[0007] The prism surface layer is disposed on the surface of the OLED red light source body;
[0008] The prism surface layer includes several strip-shaped prism bodies, one face of which is attached to the OLED red light source body, and adjacent prism bodies are closely attached to each other.
[0009] Furthermore, the height of the prism surface layer is 10-20 micrometers.
[0010] Furthermore, the diameter of the prism body is 10-20 micrometers.
[0011] Furthermore, the angle between the end of the prism body and the end away from the OLED red light source body is 45-60 degrees.
[0012] Furthermore, the OLED red light source body comprises an OLED vapor deposition stacked structure formed sequentially from top to bottom:
[0013] The structure consists of an upper substrate, a cathode layer, an EIL electron injection layer, an upper ETL electron transport layer, an upper red light emitting layer, an upper EBL electron blocking layer, an upper HTL hole transport layer, an upper CGL charge generation layer, a middle ETL electron transport layer, a middle red light emitting layer, a middle EBL electron blocking layer, a middle HTL hole transport layer, a middle CGL charge generation layer, a lower ETL electron transport layer, a lower red light emitting layer, a lower EBL electron blocking layer, a lower HTL hole transport layer, a lower HIL hole transport layer, an anode layer, and a lower substrate.
[0014] Furthermore, the thickness of the cathode layer is 2245-2255 nanometers;
[0015] The thickness of the anode layer is 130-140 nanometers, the light transmittance is greater than 85%, and the square cathode is 8-12 ohms.
[0016] Furthermore, the thickness of the upper red light emitting layer, the middle red light emitting layer, and the lower red light emitting layer is 295-305 nanometers;
[0017] The main wavelength of the upper, middle, and lower red light emitting layers is 640 nm, the color purity is Pur = 100.08, and the centroid wavelength is 650 nm.
[0018] Furthermore, the upper and lower base layers are made of transparent glass with a thickness of 0.1-2 nanometers.
[0019] The beneficial effects of this utility model are:
[0020] 1. Through the prism effect of the prism, and through the synergistic effect of refraction and total internal reflection of the prism, the incident light of the OLED red light source is refracted and totally reflected, thereby concentrating the red light of the OLED red light source inward, thus improving the light efficiency and output effect of the OLED red light source, and better outputting the red light outward.
[0021] 2. Through three layers of red light emission, it forms three times the brightness, with a deeper irradiation depth, stimulating cells deeper inside. OLED red light is closer to the solar spectrum, and photons of different wavelengths reach the cells in each layer of the subcutaneous tissue for better absorption by mitochondria. The high energy conversion rate can better activate cell regeneration and promote blood circulation.

[0032] In this embodiment, the height of the prism surface layer 1 is 10-20 micrometers. The diameter of the prism body 11 is 10-20 micrometers. The angle of the end of the prism body 11 away from the OLED red light source body 2 is 45-60 degrees.

[0034] The upper substrate 21, cathode layer 22, EIL electron injection layer 23, upper ETL electron transport layer 24, upper red light emitting layer 25, upper EBL electron blocking layer 26, upper HTL hole transport layer 27, upper CGL charge generation layer 28, middle ETL electron transport layer 29, middle red light emitting layer 210, middle EBL electron blocking layer 211, middle HTL hole transport layer 212, middle CGL charge generation layer 213, lower ETL electron transport layer 214, lower red light emitting layer 215, lower EBL electron blocking layer 216, lower HTL hole transport layer 217, lower HIL hole transport layer 218, anode layer 219, and lower substrate 220.
[0035] The cathode layer 22 has a thickness of 2245-2255 nanometers; the anode layer 219 has a thickness of 130-140 nanometers, a light transmittance of more than 85%, and a square cathode thickness of 8-12 ohms.
