Publication number: 20210127853Abstract: A tableware taking device is provided, which comprising a base and a tableware taking apparatus arranged on the base. The tableware taking apparatus is further provided with a button and a connecting rod with a first end connecting the button; the base is provided with a positioning hole in which a second end of the connecting rod is inserted for fixing the tableware taking apparatus on the base. When the button is pressed downward, the second end of the connecting rod moves away from the positioning hole for detaching the tableware taking apparatus from the base; thus the tableware taking apparatus can be placed in a better way for preventing itself from turning over. In additional, the connecting rod can be controlled by the button on the tableware taking apparatus to move away from the positioning hole in the base for detaching the tableware taking apparatus from the base.Type: ApplicationFiled: November 14, 2019Publication date: May 6, 2021Inventors: Ching Mou Lee, Chi Wai Lee

Publication number: 20210104202Abstract: In a display panel, drivers for driving LEDs of pixels are distributed over a substrate, and transceivers relay pixel data from a timing controller to the drivers. The drivers are divided into groups. Respective drivers in a group receive corresponding pixel data addressed thereto solely from one corresponding transceiver. The corresponding transceiver and the respective drivers are daisy-chained to form one first linear daisy chain, where each pair of immediately-adjacent first drivers are connected. Plural first linear daisy chains are formed for all groups. The transceivers are daisy-chained to form a second linear daisy chain by connecting each pair of immediately-adjacent transceivers. The first and second linear daisy chains form a fishbone topology network to enable transmission of pixel data from the timing controller to the drivers while reducing a data-line footprint on the substrate that mounts the pixels, driver and transceivers in comparison to a conventional star-topology network.Type: ApplicationFiled: October 4, 2019Publication date: April 8, 2021Inventors: Wing Chi Stephen CHAN, Chi Wai LEE, Pie Chih KE, Johnkid LO

Patent number: 10871854Abstract: A computing device for interacting with a user, comprising: a touch-sensing enabled display panel comprising one or more touch sensors for sensing an on-screen touch and one or more physical keys being positioned adjacent to edges of the display panel and configured to serve as off-screen keys for sensing an off-screen touch. The touch-sensing functionality is extended by coupling the touch screen with proximally positioned physical keys for detecting touch gesture such that additional gestures can be detected and in turn enhancing the computing device's user experience.Type: GrantFiled: May 13, 2019Date of Patent: December 22, 2020Assignee: Solomon Systech (Shenzhen) LimitedInventors: Wai Hon Ng, Wing Chi Stephen Chan, Chi Wai Lee, Chun Hung Lai, Johnkid Lo

Patent number: 10643519Abstract: A method is provided that allows the use of monochrome PMOLED display driver to generate grayscale patterns without the need to change the resolution of the 1-bit digital-to-analog converter (DAC) on the data line (SEG). The method further allows the elimination of extra frame buffer display memory needed by conventional techniques. This is achieved by swapping display memory space for display image pixel color (grayscale) depth in the expense of display resolution. The method further allows grayscale pattern data to be written into frame buffer only once without additional control from the host controller. The method further allows the dynamic application of grayscale on selectable whole or portion of a scan line such that full grayscale image display or a mixture of monochrome and grayscale image display in a single display panel is possible.Type: GrantFiled: July 24, 2017Date of Patent: May 5, 2020Assignee: Solomon Systech (Shenzhen) LimitedInventors: Chi Wai Lee, Chun Hung Lai, Wai Hon Ng, Yuen Pat Lau, Ling Sum Leung

Patent number: 10347174Abstract: A system enabling compressed frame scanning for a display and a method thereof are described herein. A pixel having a maximum pixel data in a row of the plurality of rows corresponding to a frame is identified. The maximum pixel data identified in the row is assigned as a pixel data for the row. A scan time for the row is computed based upon the pixel data of the row and a scanning time associated with a unit of the brightness index. An aggregate scan time for the frame is determined based upon the scan time computed for each of the plurality of rows corresponding to the frame. Finally, the frame is scanned based upon the aggregate scan time determined for the frame thereby enabling compressed scanning of the frame. The method is further implemented for randomly assigned rows of the frame to two or more sub-frames of the frame.Type: GrantFiled: November 6, 2017Date of Patent: July 9, 2019Assignee: Solomon Systech LimitedInventors: Wai Hon Ng, Chi Wai Lee, Wing Chi Stephen Chan, Ling Sum Leung

Publication number: 20090251391Abstract: A power recycling method and apparatus for driving capacitive display elements are described. The driving process involves charging and discharging the display elements. More particularly, the method effectively reuses some of the energy during the discharging process. Energy in display elements flows back from the panel to a power supply and other optionally to devices like RAM, MCU directly during the discharging process. Diodes between one or more power supplies and the display elements ensure that the discharge paths are disconnected when the voltage of display elements drops below the voltage of the power supply. A resistor path from the display elements to ground or a power supply lower than the display threshold voltage of the display elements guarantees that elements are turned OFF after the discharge process.Type: ApplicationFiled: April 2, 2008Publication date: October 8, 2009Applicant: Solomon Systech LimitedInventors: Ricky Chung Yee Ng, Felix Wai Yu Wong, Kenneth Chi Wai Lee, Stephen Wai-Yan Lai, Johnkid Lo
