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

Publication number: 20190252029Abstract: Apparatuses and techniques are described for reducing charge loss in a select gate transistor in a memory device. In one aspect, a dummy memory cell adjacent to a select gate transistor is weakly programmed during an erase operation by applying a program pulse to the dummy memory cell. The program pulse can be applied after an erase bias is applied to the memory cells and before an erase-verify test is performed, in one approach. The program pulse can be applied during the setup of the voltages for the erase-verify test. The magnitude of the program pulse can be increased in successive erase loops of an erase operation as the magnitude of a substrate voltage is also increased. The magnitude of the program pulse can also be set as an increasing function of a number of program-erase (P-E) cycles.Type: ApplicationFiled: February 15, 2018Publication date: August 15, 2019Applicant: SanDisk Technologies LLCInventors: Chun-Hung Lai, Rajdeep Gautam, Ching-Huang Lu, Shih-Chung Lee
