Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The display may include transistors with gate conductors, a first planarization layer formed over the gate conductors, one or more contacts formed in a first source-drain layer within the first planarization layer, a second planarization layer formed on the first planarization layer, one or more data lines formed in a second source-drain layer within the second planarization layer, a third planarization layer formed on the second planarization layer, and a data line shielding structure formed at least partly in a third source-drain layer within the third planarization layer. The data line shielding structure may be a routing line, a blanket layer, a mesh layer formed in one or more metal layers, and/or a data line covering another data line.

Abstract: A rotation speed detecting apparatus for a motor includes a motor; an encoder section, attached to the motor, for producing at least two encoder pulse signals each 90 degrees out of phase from the other; a control and division number setting section for controlling the rotation direction and speed of the motor according to the loaded program, setting a division number and producing a division control signal according to the set division number; a quadrupled pulse signal producing section for producing an up/down pulse signal according to the forward and reverse rotation directions of the motor on a quadrupled pulse signal and an up/down pulse signal produced according to the state transitions in the encoder pulse signals; and, a frequency dividing section for counting up or down the quadrupled pulse signal and dividing the quadrupled pulse signal by the set division number.
