Problems solved by technology

[0006] As described above, with AMOLED, visibility decreases when an image is displayed darker only to reduce current consumption, and current consumption increases when an image is displayed brighter to improve visibility
Also, when the LCD is used, when the ambient light is brighter than the brightness of the display of the mobile terminal, the visibility is reduced due to the limitation of the brightness of the backlight being used as a light source.

Abstract

A method and apparatus are provided for enhancing the readability of a character. The method includes determining ambient light of a mobile terminal and controlling background color and character color of a character image according to the determined ambient light. The method may further include performing an additional control according to the types of displays when controlling the background color and character color. Through this, it is possible to display a character image with enhanced visibility, while minimizing current consumption.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of March 3, 2011, the application number of 201110050605.8, and the title of the invention "A device and method for enhancing the readability of characters". technical field [0002] The present invention generally relates to an apparatus and method for enhancing the readability of characters in a mobile terminal, and more particularly, to a method for enhancing visibility while viewing characters on a screen of a mobile terminal. Apparatus and method for minimizing current consumption. Background technique [0003] As the use of slide-out keypads and / or touch screen displays in mobile terminals has increased, the screen sizes of mobile terminals have also increased, and displays included in mobile terminals are being continuously developed. More specifically, displays having excellent color reproduction range and contrast ratio, such as liquid crystal display (LCD) di...
