  • Publication number: 20220085000
    Abstract: A light-emitting module includes a light-emitting panel which includes a first rigid substrate, a flexible substrate, a circuit layer, a light-emitting element, and a driver chip. The flexible substrate includes a light-emitting region, a bending region, and an epitaxial region, and the light-emitting region and the epitaxial region are located on two ends of the bending region. The circuit layer includes a first connection terminal located on the epitaxial region and the driver chip is bonded to the first connection terminal. The light-emitting element is located on the light-emitting region, and the light-emitting element emits light toward the first rigid substrate. The flexible substrate is bent in the bending region and the flexible substrate in the epitaxial region is bent to a side of the light-emitting elements facing away from the first rigid substrate. The process difficulty can be reduced and the product yield can be improved.

  • Patent number: 11025764
    Abstract: A method and a system for reducing current noise of a touch terminal are provided. The method includes: determining that a user receives a voice call via an earpiece of the touch terminal, and controlling the touch terminal to switch from a first touch scan frequency to a second touch scan frequency, where the second touch scan frequency is less than the first touch scan frequency. As can be seen, if the user receives the voice call via the earpiece of the touch terminal, the touch terminal is controlled to switch from the first touch scan frequency to the second touch scan frequency, to effectively reduce the current noise heard by the user by decreasing the touch scan frequency of the touch terminal, so that the periodic current noise is outside a frequency band perceptible to a human ear, thereby improving user experience when receiving the voice call.

  • Patent number: 10325535
    Abstract: A method for testing a display panel includes: applying a first level signal to a first sub-pixel and a third sub-pixel of a first pixel unit and applying a second level signal to a second sub-pixel of the first pixel unit; applying the second level signal to a first sub-pixel and a third sub-pixel of a second pixel unit and applying the first level signal to a second sub-pixel of the second pixel unit; and detecting a short circuit between adjacent sub-pixels. The first level signal has a voltage polarity opposite to a voltage polarity of the second level signal. Therefore, it is ensured that any two adjacent sub-pixels have opposite voltage polarities when the short circuit between adjacent sub-pixels of the display panel is detected. The method also provides improved testing abilities to detect an open circuit in a sub-pixel.

During coarse scanning, in first M frames of M+N successive frames, drive lines spaced apart from one another by at least one of the drive lines are driven, and sense lines spaced apart from one another by at least one of the sense lines are detected. In the succeeding N frames of the M+N frames, there is no activity in the drive and sense lines. During the fine scanning, each drive line and each sense line within the full detection-activated region is driven and detected, respectively.
