Abstract: A transmitting device including a transmission circuit, a reception circuit and a controller is provided. The transmission circuit transmits first data by using at least one slice in a first bandwidth. The reception circuit receives second data corresponding to the first data. The controller determines the number of slices of the transmission circuit to be used in the first bandwidth based on the first data and the second data.

Abstract: A semiconductor device may include: an amplifier circuit biased by a reference current or a reference voltage and configured to amplify an input signal; a process monitoring circuit configured to output a control code signal to compensate a manufacturing process deviation of the semiconductor device; and a bias circuit configured to receive the control code signal and to change the reference current or the reference voltage based on the control code signal.

Abstract: A level shifter includes a Wilson current mirror circuit outputting an output voltage of an output node based on a first input voltage inverting a phase of an input voltage and a second input voltage inverting the phase of the first input voltage, a leakage current control circuit receiving the output voltage and controlling a leakage current generated in the Wilson current mirror circuit using the output voltage, and a latch circuit providing a voltage of a logic high level to the output node when the output voltage is a logic high level.

Abstract: A display apparatus includes a display module for displaying an image, a variable member for varying a shape of the display module, and a rear cover disposed at a rear surface of the display module and varying with the varying shape of the display module.

Abstract: An image display device comprises: a flexible display unit configured to be bent, by an external force, in a first state and a second state where the flexible display unit has different radiuses of curvature; and a middle cabinet assembly configured to cover side surfaces of the flexible display unit, wherein the middle cabinet assembly comprises: a first middle cabinet coupled to the flexible display unit, and disposed to cover a first side of the flexible display unit; and a second middle cabinet disposed to cover a second side of the flexible display unit, the second side perpendicular to the first side, and the second middle cabinet configured to perform a relative motion with respect to the first middle cabinet when the flexible display unit is transformed between the first state and the second state.
