Abstract: The application disclose a digital serializer/deserializer circuit and a data eye monitoring method thereof. A received analog signal is converted to first digital samples at a first sample rate. The first digital samples are equalized to generate a first equalized signal. A symbol decision signal is generated from the first equalized signal. The received analog signal is converted to second digital samples at a second sample rate. Difference between the first digital samples and the second digital samples is determined, and the first equalized signal and the determined difference are combined to generate a signal processing output. A data eye error rate is determined according to the symbol decision signal and the signal processing output.

Abstract: A semiconductor package includes a circuit substrate, a die, a frame structure, and a heat sink lid. The die is disposed on the circuit substrate and electrically connected with the circuit substrate. The die includes two first dies disposed side by side and separate from each other with a gap between two facing sidewalls of the two first dies. The frame structure is disposed on the circuit substrate and surrounding the die. The heat sink lid is disposed on the die and the frame structure. The head sink lid has a slit that penetrates through the heat sink lid in a thickness direction and exposes the gap between the two facing sidewalls of the two first dies.

Abstract: A display device is disclosed, which includes a display panel and a detection circuit. The display panel has pixels configured to display an image. The pixels include display and photo sensing pixels that are arranged in sensing channels. Each display and photo sensing pixel includes a display region and a photo sensing region. The display region emits light. The photo sensing region detects the light emitted by the display region and reflected from a biometric object and to convert the reflected light into photo detection signals. The detection circuit has differential signal processing circuitries that are coupled to the photo sensing regions of the display and photo sensing pixels. Each differential signal processing circuitry performs a differential operation on the photo detection signals of adjacent two of the sensing channels to generate a difference signal that is used to construct a biometric pattern corresponding to the biometric object.

Abstract: A liquid crystal display device is provided. A sub-pixel unit includes a liquid crystal capacitor, a storage circuit, and a switching circuit.
