  • Patent number: 10861367
    Abstract: According to a drive method for the display panel, m multiplex signals sequentially generate the high level pulse at the beginning of the (2i?1)th row period in a predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i?1)th row period continues until the end of the (2i?1)th row period. The m multiplex signals sequentially generate the high level pulse at the beginning of the (2i)th row period in a reverse order to the predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i)th row period continues until the end of the 2i row period. As a result, the number of times that the levels of the multiplex signals are changed in a frame period can be decreased to reduce the power consumption.

  • Patent number: 10809862
    Abstract: A touchscreen resistive sensor includes a network of resistive sensor branches coupled to a number of sensor nodes arranged at touch locations of the touchscreen. A test sequence is performed by sequentially applying to each sensor node a reference voltage level, jointly coupling to a common line the other nodes, sensing a voltage value at the common line, and declaring a short circuit condition as a result of the voltage value sensed at the common line reaching a short circuit threshold. A current value level flowing at the sensor node to which the reference voltage level is applied is sensed and a malfunction of the resistive sensor branch coupled with the sensor node to which a reference voltage level is applied is generated as a result of the current value sensed at the sensor node reaching an upper threshold or lower threshold.
