Publication number: 20240128183Abstract: A display apparatus and a display panel are disclosed. The display panel includes a display area, a driving area, and a fan-out area provided with a plurality of fan-out wirings and at least including a first section wiring connected with data signal terminals, a second section wiring connected with the first section wiring, and a third section wiring connected with the second section wiring. The fan-out wirings are close to a central axis of the driving area, so that a difference between lengths of the first section wirings on both sides and a length of the first section wiring close to the central axis is reduced, thus effectively shortening the length of the first section wiring close to the central axis when the first section wiring on both sides maintains a predetermined length, therefore, the fan-out area is compressed and a width of the display panel border is shortened.Type: ApplicationFiled: November 29, 2022Publication date: April 18, 2024Applicant: TCL China Star Optoelectronics Technology Co., Ltd.Inventor: Xin GENG

Patent number: 11322595Abstract: The disclosure provides a heterojunction bipolar transistor and a preparation method thereof. Since an emitter region has the same physical structure as a base region, and improves frequency characteristics of the device; Simultaneously with biaxial strain, uniaxial strain is introduced. Carrier transmission time in the collector region will be effectively reduced. By this structure, the width of the effective collector region is reduced, the collector junction capacitance is reduced, and the frequency characteristics of the device are further improved; an appropriate choice of the thickness of the Si cap layer can effectively reduce the accumulation of carriers at an interface and increase the gain of the device; at the same time, the preparation method of the bipolar transistor is completely compatible with a 90-nanometer CMOS process, which effectively reduces the development and manufacturing cost of the device.Type: GrantFiled: March 23, 2021Date of Patent: May 3, 2022Assignee: Yanshan UniversityInventors: Chunyu Zhou, Zuowei Li, Guanyu Wang, Xin Geng

Patent number: 7667552Abstract: A system is described for generating a discrete noise-shaped variable switching frequency signal that may be used to define a digital pulse width modulation (“PWM”) period. The system may define a switching frequency waveform that may be used to generate a current switching frequency signal as a function of a system clock. The system may quantize the current switching frequency signal to generate a discrete switching frequency signal that is realizable with the system clock. The system may detect quantization noise and input the noise into the current switching frequency signal to eliminate or reduce discrete tones at the switching frequencies of a PWM signal spectrum.Type: GrantFiled: April 10, 2007Date of Patent: February 23, 2010Assignee: Freescale Semiconductor, Inc.Inventors: Pallab Midya, Xin Geng
