Abstract

Disclosed is a keypad apparatus wherein an OLED or a TOLED (Transparent OLED) is employed to make the structure of a product slim and compact. The keypad apparatus of the present invention comprises a TOLED panel which is arranged beneath a touch panel, and a reflection sheet which is arranged beneath the TOLED panel, and which is patterned with keypad information to reflect and display the keypad information corresponding to the pixels of the TOLED panel which have emitted light. The touch panel and the TOLED panel are electrically connected to a controller. The controller senses an electrical signal for a touch point on the touch panel, and emits light from relevant pixels of the TOLED panel corresponding to the touch point.

Description

technical field [0001] The present invention generally relates to keyboards, and more particularly, to a keyboard device capable of making the product structure thin and compact by using an organic light emitting diode (OLED) or a transparent OLED (TOLED), a mobile device having the keyboard device, and controlling the device. method of the keyboard device. Background technique [0002] In general, a mobile communication terminal such as a mobile phone is equipped with a keypad for various types of information search, transmission and reception, or character input. [0003] By adhering a substrate on a printed circuit board (PCB) with a printed circuit pattern, a membrane switch and a light emitting diode (LED) for backlighting are provided on the substrate, and Korean consonants and vowels, English consonants and vowels are printed on the substrate. The upper sheet of letters, numbers, etc. is used to construct a typical traditional keyboard. [0004] However, the convent...
