Abstract

Herein disclosed is a mobile phone capable of receiving TV broadcasting, including a first housing having a display unit on a front face thereof and a sub-display unit on a back face thereof, and a second housing having an operation unit on a surface thereof, the first housing and the second housing being coupled via a biaxial hinge, and the mobile phone 30 can be off-hooked for starting the phone communication merely by detection of a change in housing form upon detection of an incoming call, from a TV viewing form in a portrait or landscape orientation in a folded state, a TV viewing form in the landscape orientation with the first housing 31 being inclined by 90 degrees, a TV viewing form in a control information display mode, and a TV viewing form in the phone communication mode.

Description

technical field [0001] The present invention relates to a mobile phone with a digital TV (DTV) viewing function that can be switched to a phone communication mode by a simple operation when a call is received while watching TV. Background technique [0002] In recent years, mobile phones with TV viewing functions have been developed and put into practical use. For such mobile phones, various schemes have been proposed to improve the performance not only concerning TV visibility and security, but also functions required for telephone communication. [0003] For example, a mobile phone having a two-axis hinge structure has been developed, which includes a first housing rotatable around a first hinge connected to a lower end portion thereof, and wherein the first hinge is positioned relative to the The orthogonal direction of the first hinge is fixed to the second hinge, and the second hinge is rotatably connected to the upper end portion of the second housing so as to allow t...
