Description

Technical Field

[0001] This utility model relates to the field of OLED display technology, specifically to a thin, light, energy-saving and environmentally friendly OLED display. Background Technology

[0002] OLED, also known as organic electroluminescent display or organic light-emitting semiconductor, is a current-driven organic light-emitting device. It emits light through the injection and recombination of charge carriers, and the luminous intensity is directly proportional to the injected current. Under the influence of an electric field, holes generated at the anode and electrons generated at the cathode move and are injected into the hole transport layer and electron transport layer, respectively, migrating to the light-emitting layer. When these two electrons meet in the light-emitting layer, they generate excitons, which excite the light-emitting molecules to ultimately produce visible light.

[0003] For example, Chinese Patent 202223371430.3 proposes an OLED display screen that fits a thinner OLED display screen into a frame and is fixed by a back plate on the back. The corner protectors at the four corners of the frame can effectively protect the four corners of the thinner OLED display screen and reduce damage to the four corners of the OLED display screen caused by bumps.

[0004] However, the above technical solutions lack a heat dissipation structure. Simply opening heat dissipation holes is insufficient to absorb the heat generated when the OLED display is working. If the internal components of the OLED display are damaged due to excessive heat when the ambient temperature is high, a thin, energy-saving and environmentally friendly OLED display is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a thin, light, energy-saving, and environmentally friendly OLED display screen. It has advantages such as improved heat dissipation and increased service life. It solves the problem that existing OLED display screen solutions lack heat dissipation structures and cannot absorb the heat generated during OLED display operation by simply opening heat dissipation holes. This can lead to the burning of internal components of the OLED display screen when the ambient temperature is high.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thin, light, energy-saving, and environmentally friendly OLED display screen, including a housing, an mounting groove on the outer surface of the housing, an OLED screen embedded inside the housing, an OLED light-emitting component embedded inside the housing, a heat dissipation component fixedly installed inside the housing, and an anti-collision housing fixedly installed on the outer surface of the housing;

[0007] The heat dissipation assembly includes a heat dissipation box, which is embedded inside the outer shell. An inlet pipe is fixedly installed on the left side inside the heat dissipation box, and a sealing cap is threaded to the top of the inlet pipe. A heat dissipation pipe is fixedly installed at the bottom of the inlet pipe, and an outlet pipe is fixedly installed at the right end of the heat dissipation pipe. A circulation pipe is fixedly installed at the top of the outlet pipe. A guide post is fixedly installed inside the heat dissipation box, and mounting holes are provided on the heat dissipation box.

[0008] Furthermore, the anti-collision shell is fixedly installed on the outer surface of the shell through the mounting groove, and the anti-collision shell is a rectangular frame.

[0009] Furthermore, the OLED screen is embedded in the front of the housing, and the OLED light-emitting component is electrically connected to the OLED screen via wires.

[0010] Furthermore, the OLED light-emitting component is composed of a substrate, a cathode, an anode, a hole injection layer, an electron injection layer, a hole transport layer, an electron transport layer, an electron blocking layer, a hole blocking layer, and a light-emitting layer.

[0011] Furthermore, the OLED light-emitting component is installed inside the mounting hole, and the heat dissipation component is located on the back of the OLED screen, outside the OLED light-emitting component.

[0012] Furthermore, the guide pillars are arranged at equal intervals, and the heat dissipation pipes are designed to spiral around the guide pillars.

[0013] Furthermore, the two ends of the circulation pipe are fixedly connected to the inlet pipe and the outlet pipe, respectively, and the interior of the heat dissipation pipe is filled with coolant.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This thin, light, energy-saving, and environmentally friendly OLED display features a heat dissipation system. When the OLED screen and its light-emitting components are in operation, they generate a significant amount of heat, which is absorbed and dissipated by the heat dissipation system. The heat dissipation pipes are filled with coolant, which circulates within the inlet, outlet, and circulation pipes. Due to thermal conduction, heat is transferred to the coolant, which in turn absorbs the heat, thus cooling the internal components of the OLED display. Additionally, an impact-resistant outer shell enhances the OLED display's protection, effectively extending its lifespan. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The thin, light-emitting, energy-saving and environmentally friendly OLED display in this embodiment includes a housing 1, an installation groove 2 on the outer surface of the housing 1, an OLED screen 3 embedded inside the housing 1, an OLED light-emitting component 4 embedded inside the housing 1, a heat dissipation component 5 fixedly installed inside the housing 1, and an anti-collision housing 6 fixedly installed on the outer surface of the housing 1.

[0023] The heat dissipation assembly 5 includes a heat dissipation box 501, which is embedded inside the outer shell 1. An inlet pipe 502 is fixedly installed on the left side inside the heat dissipation box 501. A sealing cap 503 is threadedly connected to the top end of the inlet pipe 502. A heat dissipation pipe 504 is fixedly installed at the bottom end of the inlet pipe 502. An outlet pipe 505 is fixedly installed at the right end of the heat dissipation pipe 504. A circulation pipe 506 is fixedly installed at the top end of the outlet pipe 505. A guide post 507 is fixedly installed inside the heat dissipation box 501. An installation hole 508 is provided on the heat dissipation box 501.

[0024] In this embodiment, the mounting groove 2 on the outer surface of the housing 1 is used to install the anti-collision housing 6. The anti-vibration housing 6 is rectangular and is embedded in the interior of the mounting groove 2. The anti-collision housing 6 can increase the anti-collision effect of the OLED display, avoid damage to the OLED display from impacts, and effectively improve the service life of the OLED display.

[0025] In this embodiment, the OLED screen 3 is embedded in the front of the housing 1, and the OLED light-emitting component 4 is electrically connected to the OLED screen 3 through wires. The OLED light-emitting component 4 is installed inside the mounting hole 508, and the heat dissipation component 5 is located on the back of the OLED screen 3 and outside the OLED light-emitting component 4. The OLED light-emitting component 4 is composed of a substrate, a cathode, an anode, a hole injection layer, an electron injection layer, a hole transport layer, an electron transport layer, an electron blocking layer, a hole blocking layer, and a light-emitting layer.

[0026] Specifically, the substrate is the foundation of the entire device; all functional layers need to be deposited onto the substrate. Glass is typically used as the substrate, but for flexible OLED devices, other materials such as plastics are required. The anode is connected to the positive terminal of the applied driving voltage. Holes in the anode move towards the light-emitting layer under the influence of the applied voltage. The anode needs to have a certain degree of light transmittance during device operation so that the light emitted from within the device can be observed from the outside. The most commonly used material for the anode is ITO. The hole injection layer modifies the anode of the device and allows holes from the anode to be smoothly injected into the hole transport layer. The hole transport layer is responsible for transporting holes to the light-emitting layer. The electron blocking layer blocks electrons from the cathode at the interface of the light-emitting layer, increasing the electron concentration at the interface. The light-emitting layer is where electrons and holes recombine to form excitons, which then de-excite light. The hole blocking layer blocks holes from the anode at the interface of the light-emitting layer, thereby increasing the probability of electron-hole recombination at the interface and increasing the luminous efficiency of the device. The electron transport layer is responsible for transporting electrons from the cathode to the light-emitting layer. The electron injection layer modifies the cathode and transports electrons to the electron transport layer. Electrons in the cathode move towards the light-emitting layer under the drive of an external driving voltage, and then recombine with holes from the anode in the light-emitting layer.

[0027] In this embodiment, the guide posts 507 are arranged at equal intervals, the heat dissipation pipes 504 are designed to spiral around the guide posts 507, the two ends of the circulation pipe 506 are fixedly connected to the inlet pipe 502 and the outlet pipe 505 respectively, and the inside of the heat dissipation pipes 504 is filled with coolant.

[0028] During implementation, when the OLED display is working, the internal OLED screen 3 and OLED light-emitting component 4 will generate a large amount of heat. The heat will be absorbed and dissipated by the heat dissipation component 5. The heat dissipation pipe 504 is too small to hold the coolant. The coolant circulates inside the inlet pipe 502, heat dissipation pipe 504, outlet pipe 505 and circulation pipe 506. Due to the effect of heat conduction, the heat will be transferred to the coolant, and the coolant will absorb the heat.

[0029] In summary, this thin, light, energy-saving, and environmentally friendly OLED display, through the inclusion of a heat dissipation component 5, allows heat to be transferred to the coolant via thermal conduction. The coolant then absorbs the heat, thus dissipating heat from the inside of the OLED display. Simultaneously, the addition of an anti-collision shell 6 enhances the OLED display's protection, effectively increasing its lifespan. This addresses the problem of existing OLED display solutions lacking a proper heat dissipation structure, which relies solely on ventilation holes to absorb the heat generated during operation. Furthermore, this can lead to overheating and damage to internal components in high-temperature environments.
