Problems solved by technology

However, in order to achieve the effect of reducing the size and weight of the cellular phone, it is impossible to provide a space for indicating letter input keys
Therefore, in ordinary cellular phones, the number input keys also perform the function of alphabet input keys, or an externally connected keyboard for inputting letters has been used in cellular phones, because inputting letters is not easy or carrying letters in addition to the cellular phone Enter the keyboard, which will cause trouble for the user

Abstract

An electronic device with a liquid crystal display (LCD), such as a foldable cellular phone, improves the visibility of the LCD by making the content displayed on the LCD visible even when the device is closed. The foldable electronic device includes: a display unit casing and an operating unit casing, which are connected by a hinge in a manner that allows each casing to rotate. The display unit housing is fitted with a projected LCD which is visible on both sides, and the operating unit housing has input keys. The device also includes a display control means for controlling whether the LCD needs to display reversed display content according to whether the user views the LCD from the front or from the back. A surface of the operation unit cabinet which is in face-to-face contact with the LCD when the device is folded is subjected to reflective processing for reflecting light to the LCD. In addition, a light source provided inside the operating unit for illuminating the input keys also illuminates the LCD when the device is folded.

Description

Technical field: [0001] The present invention relates to an electronic device with a liquid crystal display (LCD), such as a foldable cellular phone, which device comprises a display unit housing on which the LCD is provided, and an operation unit housing providing an input keyboard, etc., The two are connected to each other in such a way that the device can be folded. Background technique [0002] 1( a ) and FIG. 1( b ) are schematic diagrams illustrating the invention by taking a general foldable cellular phone as an example of a common electronic device with LCD. The cellular phone is folded (opened) in FIG. 1(a), and the cellular phone is folded (closed) in FIG. 1(b). [0003] As can be seen from FIGS. 1(a) and 1(b), a general foldable cellular phone includes a display unit case 121 and an operation unit case 122 connected by a hinge 123 so as to be foldable. The display unit casing 121 can be rotated in the direction indicated by the arrow A wit...
