Folder-type mobile communication terminal having double-sided LCD
View Patent ↗A folder-type mobile communication terminal having a double-sided LCD includes a first LCD panel, a second LCD panel, and a backlight device, which is interposed between the first and second LCD panels, for bi-directionally illuminating the first and second LCD panels, wherein the backlight device includes a light emitting diode for emitting light and a light guide plate for distributing the light emitted from the light emitting diode to the first and second LCD panels.
1. A folder-type mobile communication terminal having a double-sided LCD, comprising:
a first LCD panel;
a second LCD panel; and
a backlight means, which is interposed between the first and second LCD panels, for bi-directionally illuminating the first and second LCD panels, wherein the backlight means includes:
a single light emitting means for emitting light; and
a single light guide plate for distributing the light emitted from the light emitting means to the first and second LCD panels.
2. The folder-type mobile communication terminal as recited in claim 1 , wherein the backlight means further includes two translucent films disposed on both planes of the single light guide plate.
3. The folder-type mobile communication terminal as recited in claim 2 , wherein the single light guide plate dominantly distributes uniform light to the first LCD and generates leakage light toward the second LCD.
4. The folder-type mobile communication terminal as recited in claim 3 , wherein the two translucent films include:
a first translucent film disposed between one plane of the single light guide plate and the first LCD panel for uniformly transmitting the uniform light to the first LCD panel; and
a second translucent film disposed between the other plane of the single light guide plate and the second LCD panel for uniformly transmitting the leakage light to the second LCD panel, wherein a light transmissivity of the first translucent film is higher than that of the second translucent film.
5. The folder-type mobile communication terminal as recited in claim 4 , wherein the backlight means further includes a light collecting means formed at an upper portion of the single light guide plate for collecting the light emitted from the light emitting area.
6. The folder-type mobile communication terminal as recited in claim 4 , further comprising a power control means for controlling power of the first and second LCD panels, wherein the power control means controls that the first and second LCD panels are simultaneously or selectively illuminated according to flip stats, opening and shutting of the flip of the folder-type mobile communication terminal.
7. The folder-type mobile communication terminal as recited in claim 4 , wherein the light emitting means includes three colors (R, G and B) LCD emitting device.
8. The folder-type mobile communication terminal as recited in claim 4 , wherein the light emitting means is substantially a light emitting diode (LED).
9. The folder-type mobile communication terminal as recited in claim 4 , wherein the light emitting means is substantially a fluorescent lamp.
