Abstract

A mobile terminal and a method for displaying event occurrence notification data of the mobile terminal are provided to solve a problem that when a character or an image is displayed in an OSD method, a user can hardly discriminate the character and the image in case that the color of the character or the image is the same as or similar to the color of the OSD display region. When an event of the second function occurs while the first function is being operated, a calculating unit(172) calculates average R, G and B values of a certain region of a screen operated according to the first function. An acquiring unit(173) acquires a gray scale value of the certain region by using the calculated average R, G and B values. A conversion unit(174) converts the color of display data according to the occurred event into a color corresponding to a gray scale value different from the gray scale value acquired by the acquiring unit. A display unit displays the converted display data at the certain region.
