Embodiment 1
[0013] like figure 1 ——As shown in 4, this easy-to-clean organic light-emitting display interface structure includes a substrate 1 and an interface 2 located on the substrate. The interface 2 is protected by a polymer positive or negative polymer photosensitive film 3 with a thickness less than 1um.
[0014] like Figure 5 As shown, a photosensitive film is formed on the organic display interface 2 and then covered with an organic luminescent material film 4 and a sealing film 5 . Use excimer laser technology (wavelength is 248nm) to process and clean the interface, the polymer photosensitive film 3, and the multi-layer pollutants on it, are activated and evaporated under the ablation of the excimer laser beam with a wavelength of 248nm, without The clean interface of any sundries is exposed, so that the interface of the organic light-emitting display can achieve high-quality cleanliness and meet the requirements for crimping wires.

The invention relates to the field of organic light emitting, and discloses an easy-cleaning interface structure of an OLED, which comprises a base plate and an interface arranged on the base plate. The interface structure is characterized in that the interface is coated with a sensitive layer which has a size larger than that of the interface of the OLED and a thickness smaller than 1 Mum; and the sensitive layer is a macromolecule positive or negative photoresist sensitive layer. The invention overcomes the defect that the interface of the prior OLED can not be cleaned conveniently. The high phototonus of the sensitive layer is utilized and laser is used for cleaning the interface of the OLED; the sensitive layer and the contamination adhered thereto are activated and vaporized under the ablation of laser beams; and a clean interface without any contamination is exposed, so that the interface of the OLED can realize the high-grade cleanness and meet the requirements for line-pressing at the later stage so as to ensure higher precision of the product.
Description
technical field [0001] The invention relates to the field of organic luminescence, in particular to an interface structure of an organic luminescence display which is easy to clean. Background technique [0002] In the field of microelectronics, the cleaning of devices and material surfaces has always been an important part of scientific research. With the development of modern science and technology, the scale of electronic devices and the matching gap between precision machinery are getting smaller and smaller, and the pollution of micron-sized particles will also cause great harm. In the semiconductor chip packaging process, the semiconductor chip is hand-attached and mounted on the printed circuit board, and the electrical connection between the chip and the substrate is realized by wire stitching and covered with resin to ensure reliability. The part where the chip and the substrate establish an electrical connection is the interface. During the manufacturing process ...
