  • Patent number: 10147772
    Abstract: A flexible OLED display device that includes an upper module having a cover window film, a lower module, and a display module between the upper and lower modules. The display module includes an OLED and an OLED substrate. The stiffnesses of components in the display device are controlled to satisfy a particular relationship such that the bending stiffnesses of the upper and lower modules are tuned in order to position the neutral bending plane below the display module, which places the display into a state of compressive strain as opposed to zero strain. This design is suitable for a bifold flexible display in which the upper module can be folded to face itself.

  • Patent number: 10126343
    Abstract: The invention provides an ESD detection method for array substrate. By connecting the first metal layer on array substrate through the first wire to the first test point, connecting the second metal layer on array substrate through the second wire to the second test point, when ESD occurs on array substrate, the resistance detection device is used to measure the resistance between the first and second test points. If the resistance is positive infinity, ESD did not occur between the first and second metal layers; if the resistance is within a measurable range, ESD occurs between the first and second metal layers. The resistance is used to locate the location of ESD occurrence on array substrate. Compared to known method using microscope to search ESD location, the invention can locate ESD location on array substrate more accurately and rapidly to save time and labor as well as detection cost.

  • Patent number: 10088711
    Abstract: At a corner of a TFT substrate where sealants are coated overlapping each other, a phenomenon that the sealants protrude into the display region is prevented by a structure that: the TFT substrate having an organic passivation film is formed as far as the outside of the display region. A groove-like organic passivation film removed portion is formed surrounding the display region. Since the sealants are coated overlapping each other at the corner, when a TFT substrate and a counter substrate are superposed at a predetermined gap, the width of the groove-like organic passivation film removed portion is made larger at the corner than the side in order to prevent the sealant from extending. Since an excessive sealant is absorbed in the groove-like organic passivation film removing portion of a larger width at the corner, the sealant can be prevented from protruding to the inside of the display region.
