Description

Technical Field

[0001] This utility model relates to the field of AMOLED screen technology, specifically a high-brightness AMOLED screen. Background Technology

[0002] AMOLED screens are a self-emissive display technology where each pixel emits light independently, eliminating the need for backlighting. They feature high contrast, a wide color gamut, and ultra-fast response times, offering more vibrant colors, deeper blacks, and lower power consumption. They also support flexible designs, making them suitable for thin, flexible electronic devices. They are primarily used in high-end smartphones, smartwatches, VR devices, and future innovative products such as foldable screens, automotive displays, and smart home devices. However, current AMOLED screens still have the following shortcomings: For example, patent document CN217768382U discloses an AMOLED display. This AMOLED display has a tempered glass plate attached to one side of the AMOLED panel and a buffer layer attached to the other side of the AMOLED panel. This allows the AMOLED display to cushion external impacts and improve its impact resistance, making it less likely to be damaged by accidental drops. However, its overall brightness is low, and it cannot maintain overall performance while maintaining brightness, making it unsuitable for outdoor strong light or HDR scenarios. Utility Model Content

The reinforcing component is disposed on the surface of the touch layer and includes a TFE encapsulation layer, a transparent MicroLED layer, a cathode layer, an ETL layer, an EML light-emitting layer, an HTL layer, an anode layer, a high thermal conductivity substrate, a graphene heat dissipation layer, and a TFT backplane. The TFE encapsulation layer is disposed on the lower surface of the touch layer and adopts multi-layer TFE encapsulation. A transparent MicroLED layer is disposed on the lower surface of the TFE encapsulation layer and is processed by photolithography. A cathode layer is disposed on the lower surface of the transparent MicroLED layer, and an ETL layer is installed on the lower surface of the cathode layer.
