Questions about Electroluminescent Display Devices: 1. How does the absence of the organic layer at the laser ablation area impact the functionality of the display device? The absence of the organic layer at the laser ablation area ensures precise control over the display's active area, leading to improved performance and longevity.
2. What are the key advantages of using a planarization layer in the construction of electroluminescent display devices? The planarization layer helps to create a smooth and uniform surface for the deposition of subsequent layers, resulting in better overall device performance and reliability.
Original Abstract Submitted
An electroluminescent display device includes a substrate including an active area and a non-active area surrounding the active area; a planarization layer over the substrate; an anode on the planarization layer; an organic layer on the anode and absent at a laser ablation area in the non-active area to surround the active area, a portion of the organic layer disposed outside the laser ablation area; a cathode on the organic layer and absent at the laser ablation area, a portion of the cathode disposed outside the laser ablation area; an encapsulation substrate above the substrate; and a dam at the laser ablation area between the substrate and the encapsulation substrate.
