In order to achieve the above object, the utility model is a kind of portable mobile termianl with preposition leaded light display screen, comprise portable terminal casing and inner printed circuit board (PCB), also comprise Transflective liquid crystal display screen and light-emitting diode, described Transflective liquid crystal display screen and light-emitting diode are placed on the same side of printed circuit board (PCB), and wherein light-emitting diode is placed on the peripheral position of Transflective liquid crystal display screen.
In the technical scheme that the utility model proposed, also have following technical characterictic:
Optical inductor is used for the light intensity of mobile terminal receive surrounding environment, and the light intensity data are sent to central controller;
Central controller is judged whether the light intensity data have reached to set in advance, if bright and clear, then closes light-emitting diode, if insufficient light is then opened light-emitting diode.
In the technical scheme that the utility model proposed, also have following technical characterictic:
Button is used to receive user's incoming signalling and opens and closes light-emitting diode.Described button is a button that increases newly, also can be existing any one button on the portable terminal.The embodiment button is the delete key of portable terminal, opens or close light-emitting diode under holding state.
In the technical scheme that the utility model proposed, further improvement also has following technical characterictic:
Light guide plate is placed on the upper strata of light-emitting diode, is used for light is reflexed to described Transflective liquid crystal display screen, and the bottom of described light guide plate is screwed on the portable terminal printed circuit board (PCB), described casing midsole layer light reflecting membrane.
In the technical scheme that the utility model proposed, further improvement also has following technical characterictic:
Described light-emitting diode is two, is placed on the upper and lower side position of described Transflective liquid crystal display screen respectively.
Technique effect and the advantage that the utlity model has are, because LCDs has anti-saturating property, under outdoor well-lighted situation, can utilize the light reflection of surrounding environment, under the situation of external surrounding environment light deficiency, open the light-emitting diode that portable terminal carries and illuminate LCDs, can save the power supply use amount of portable mobile termianl in a large number.The power of external light no matter, the display screen on the portable terminal can both provide good visual effect.

Embodiment
The utility model provides a kind of portable mobile termianl with preposition leaded light display screen, portable terminal all can use under any lighting environment easily, the strong place of light out of doors particularly, its display frame is very clear, under the situation of dim light, illuminate the needs that screen satisfies the user by the LED of portable terminal.
In order to make those skilled in the art person understand the utility model scheme better, and make the purpose of this utility model, feature and advantage can become apparent more, below in conjunction with the drawings and specific embodiments the utility model are described in further detail.
Theory diagram of the present utility model as shown in Figure 1, optical sensor 2 is used to receive the light intensity of surrounding environment, and the light intensity of surrounding environment is converted to data send to central controller 1, central controller 1 judges whether the light intensity data have reached setting in advance and control and whether LED light-emitting diode 4 is opened or closed, if light intensity data have reached the requirement that is provided with in advance, then close LED light-emitting diode 4, LCD display 3 is utilized surrounding environment to carry out the light reflection and is had good visual effect.If the light intensity data can not reach the requirement that is provided with in advance, then open LED light-emitting diode 4, LCD display 3 uses LED light-emitting diode 4 that screen is lighted.
Another technical scheme as shown in Figure 2, adopt a kind of more simple and practical mode, cancellation optical sensor 2, control LED light-emitting diode 4 with the some buttons 5 on the cell phone keyboard, if user 6 finds that LCD display can not reach requirement, then user 6 clicks button 5 and opens LED light-emitting diode 4, and the light of LED light-emitting diode 4 reflexes to LCD display, thereby improve the brightness and the visual effect of LCD display, reach user's requirement.Wherein button 5 can be selected any one button on the mobile phone, the control button that to indicate this button 5 in operation instruction are LED light-emitting diodes 4, this technical scheme can freely control whether open LED light-emitting diode 4 by user 6, and has saved the cost of optical sensor.
