Embodiment
At first see also Fig. 1, Fig. 1 is the electrical block diagram according to the mobile phone of first embodiment of the invention.As shown in Figure 1, the mobile phone according to first embodiment of the invention comprises: control chip 101 is used to obtain the ambient light compensation triggering signal, and produces control signal according to the ambient light compensation triggering signal; Ambient light compensation module 102, luminous under the control of control signal, so that mobile phone display screen (not illustrating) surround lighting is on every side compensated.Wherein, control chip 101 can be preferably the baseband processing chip in the mobile phone, but, also can choose respective chip according to actual needs with controlled function.
Mobile phone further comprises backlight module 103, backlight module 103 is arranged at the below of mobile phone display screen, to provide backlight to mobile phone display screen, control chip 101 is after obtaining the ambient light compensation triggering signal, further turn down the luminosity of backlight module 103, make the light that mobile phone display screen sends and the contrast of surround lighting further reduce.
Please continue referring to Fig. 1, mobile phone also comprises button 104, pushed button 104 o'clock the user, this button 104 can produce the ambient light compensation triggering signal to control chip 101, control chip 101 produces control signal according to the ambient light compensation triggering signal, and control signal is sent to ambient light compensation module 102, and ambient light compensation module 102 can be luminous under the control of control signal, so that the surround lighting around the mobile phone display screen is compensated.
It should be noted that, above-mentioned button 104 can be arranged on the side of mobile phone, when the user thinks that light more secretly need be opened ambient light compensation, as long as push button 104, button 104 sends the ambient light compensation triggering signal to control chip 101 in the back that is pressed, control chip 101 is opened ambient light compensation module 102, to carry out ambient light compensation.And, except that the mode of using button 104, the present invention also can produce the ambient light compensation triggering signal by other modes, for example, can utilize the brightness of luminance sensor induction current environment, and be sent to control chip 101 and analyze, if control chip 101 determines current environment brightness when being lower than a certain threshold level, then produce the ambient light compensation triggering signal, and further check and accept control signal according to the ambient light compensation triggering signal, wherein, above-mentioned threshold value can be by experiment statistics gained repeatedly.
See also Fig. 2, Fig. 2 is the electrical block diagram according to the mobile phone of second embodiment of the invention, compares with first embodiment, has been described in further detail the circuit structure of ambient light compensation module 202 in this enforcement.
As shown in Figure 2, ambient light compensation module 202 comprises: a plurality of light-emitting diodes 205,206,207,208 and controlled switch 209, wherein, a plurality of light-emitting diodes 205,206,207,208 are arranged in parallel, and its positive pole is connected with cellular phone power supplies 210, first end 2091 of controlled switch 209 is connected with the negative pole of a plurality of light-emitting diodes 205,206,207,208, second end 2092 is connected with control chip, to receive control signal, the 3rd end 2093 ground connection, first end 2091 and the 3rd end 2093 conducting under the control of control signal.
It should be noted that for convenience of explanation, only in Fig. 2, show 4 light-emitting diodes, but in actual applications, its concrete quantity is also done concrete the qualification, but chooses according to actual needs.
In a preferred embodiment of the invention, ambient light compensation module 202 can further comprise a plurality of current-limiting resistances 211,212,213,214, the current-limiting resistance setting of connecting with light-emitting diode respectively, limit with the size of current to the light-emitting diode of flowing through respectively, thereby guarantee that light-emitting diode is normally luminous.
And in other execution modes of the present invention, also can power supply be provided to the positive pole that a plurality of light-emitting diodes 205,206,207,208 are provided by the VBAT port of control chip 201.In addition, the positive pole of a plurality of light-emitting diodes 205,206,207,208 also can directly be connected with the cathode output end of battery of mobile phone or the power output end of power management chip, and the present invention does not do concrete restriction to it.And a plurality of light-emitting diodes 205,206,207,208 are preferably disposed on the back side of mobile phone, shine directly into user's eyes to avoid the light that it was sent as far as possible, and user's glasses are damaged.
