A user terminal device is provided. The user terminal device includes a display, a first sensor provided on a front surface of the user terminal device and configured to detect a front illumination, a second sensor provided on a rear surface of the user terminal device and configured to detect a rear illumination, and a controller configured to adjust a luminance of the display based on the front illumination detected by the first sensor and the rear illumination detected by the second sensor.

User terminal device and method for adjusting luminance thereof

An oil injection apparatus includes: a storage unit extruding lubricating oil through an ejection hole formed at a lower end thereof; a discharge unit communicating with the storage through the ejection hole and discharging the lubricating oil outside according to a pumping operation; a plurality of discharge pumps arranged at regular intervals in a circumferential direction of the discharge unit and having respective first ends disposed in the discharge unit; and a driving unit rotating in a direction to sequentially press the first ends of the discharge pumps, which are disposed in the discharge unit, thereby causing the discharge pumps to perform the pumping operation in turn.

Oil injection apparatus

Provided is a display system. The display system includes: a display; a sensor that senses light that is irradiated onto the surface of the display; and a controller that locally adjusts the luminance of a partial area in which visibility deteriorates as a result of the irradiated light in all display areas of the display.

Display system for enhancing visibility and methods thereof

A protection case and an electronic device using the same are provided. The protection case includes a base cover in which an electronic device including a main display is accommodated, a flip cover, which includes an auxiliary display on a front surface portion of the flip cover, and a connection portion, which connects the flip cover to the base cover. When the main display is covered with the flip cover, the flip cover is converted to a closed position. When the main display is exposed, the flip cover is converted to an opened position. When the flip cover is in the closed position and the auxiliary display is hidden, the auxiliary display is converted to a first position, and when the flip cover is in the closed position and the auxiliary display is exposed, the auxiliary display is converted to a second position.
