An electronic apparatus includes a host, a touch control screen, a pivot unit, a retaining unit, and a control unit. The retaining unit includes a driving member electrically operable to drive a retaining member to move between a retaining position and a non-retaining position. The control unit controls, according to an operation signal corresponding to a status of the touch control screen, the driving member to drive the retaining member to either move to the retaining position for resisting rotation of the touch control screen relative to the host, or move to the non-retaining position for not resisting rotation of the touch control screen relative to the host.

A display panel subsystem adaptively employs one of three types of input offset voltage cancellation modes based on an analysis of gray level values of sub-pixels for each row un a frame of image data. The system selects a candidate row within a selected group of rows and applies a first chopper mode to each sub-pixel in the candidate row. Under a row-based mode, the system applies a second chopper mode to each sub-pixel included in a row having gray level values matching the candidate row. Under a per-column row-based mode, the system applies the row-based mode on a per-column basis. Under a sub-pixel-wise mode, for each column, the system changes a chopper mode applied to a sub-pixel in a subsequent row relative to the last state of the chopper mode in a row having the same gray level value as a corresponding sub-pixel in the subsequent row.

A touch key of an operation console includes a circuit board (310) having a light source (312, 314), a light transmitting portion (322) transmitting light, a non-transparent light shielding portion (324) and a semi-transparent operation panel (300) covering upper surfaces of the light transmitting portion and the light shielding portion.
