Patent number: 11481058Abstract: The disclosure provides a touch display device, a touch display panel, a touch display panel and a driving method. The touch display panel includes a first substrate, multiple micro light emitting devices, multiple micro driving devices and multiple touch driving electrodes. Each micro driving device corresponds to the multiple micro light emitting devices to drive the multiple micro light emitting devices to emit light. At least one touch driving electrode corresponds to at least one micro driving device. The touch driving electrode receives a signal transmitted to a corresponding micro driving device as a touch driving signal, or, the touch driving electrode receives a signal outputted by the corresponding micro driving device as the touch driving signal. Therefore, there is no need for a main driver chip to provide the touch driving signal to the touch driving electrode. Thus, the power consumption of the main driver chip is greatly reduced.Type: GrantFiled: July 6, 2021Date of Patent: October 25, 2022Assignee: Shanghai Tianma Micro-Electronics Co., Ltd.Inventor: Yingteng Zhai

Patent number: 11481070Abstract: Touch sensing performance can be improved using display noise correction. In some examples, a touch sensor panel in proximity to a display can capture a first touch image from a touch sensor panel concurrently with updating the display and a second touch image from the touch sensor panel concurrently with blanking the display (e.g., while the display is not updating). A composite touch image can be generated by summing a filtered first touch image and a filtered second touch image. The composite touch image can be further filtered using robust regression techniques to remove residual display noise.Type: GrantFiled: August 31, 2021Date of Patent: October 25, 2022Assignee: Apple Inc.Inventors: Daniel Ganjali, Michael Robert White

Patent number: 11467685Abstract: Embodiments disclosed herein relate to a touch display panel and a touch display device. By arranging a shielding structure, which is connected to a touch electrode in a region where a touch line and a data line overlap each other or is applied with a shielding signal corresponding to a touch driving signal from an outside circuit, between the touch line and the data line, it is possible to prevent direct capacitance from being formed between the touch line and the data line, and to prevent the capacitance formed due to the data line from causing noise on a touch sensing signal. In addition, by arranging a touch load reduction layer between the shielding structure and the touch line, it is also possible to reduce the capacitance between the touch line and the data line arranged in the horizontal direction, thereby improving touch sensing performance.Type: GrantFiled: April 30, 2021Date of Patent: October 11, 2022Assignee: LG Display Co., Ltd.Inventors: HoonBae Kim, CheolSe Kim, SeungMok Shin, JuHan Kim, YongChan Park, HyunHo Park
