Embodiment
The present invention provides a kind of portable terminal and brightness control method thereof with the glo-stick function, and is clearer, clear and definite for making the object of the invention, technical scheme and effect, below to further explain of the present invention.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1; Fig. 1 is the structured flowchart of the portable terminal preferred embodiment of band glo-stick function of the present invention; As shown in the figure, it comprises: gyroscope 100, baseband chip 200, backlight 300, said gyroscope 100, baseband chip 200, backlight 300 connect successively.Core of the present invention is exactly the angular speed when utilizing gyroscope 100 to respond to portable terminal to brandish, thereby adjusts the brightness of backlight 300 according to this angular speed, reaches the purpose that realizes simulation glo-stick effect.Carry out detailed description in the face of the each several part among the present invention down.
Gyroscope 100 among the present invention; Be mainly used in the angular speed of induction portable terminal when brandishing, gyroscope is a kind of angular movement checkout gear, has a gyroscope chip in the gyroscope 100 in the present invention; It is gyro sensor; It is simple and easy to usefulness based on free space move with gesture location and control system, in addition, the gyroscope 100 among the present invention can also be a lasergyro; Its principle is to utilize optical path difference to measure angular velocity of rotation; In the closed light path of lasergyro, by same light source send along clockwise direction with the two-beam and the interference of light of counter-clockwise direction transmission, utilize detected phase difference or change of interference fringes can measure closed light path angular velocity of rotation;
In the present invention, also need define the direction of gyroscope 100, for example; As shown in Figure 2, definition gyroscope 100 with the Z axle be rotating shaft rotate counterclockwise direction for just, then portable terminal is that the angular speed that clockwise rotates of rotating shaft is for bearing with the Z axle; The angular speed that rotates counterclockwise that when portable terminal with the Z axle is rotating shaft is for just; Like Fig. 3 and shown in Figure 4, the angular speed of rotation direction shown in Figure 3 is for just, and rotation direction shown in Figure 4 is for negative.
Further; Gyroscope 100 among the present invention is a single axis gyroscope, and it can detect the angular speed on the face, and the present invention also can adopt dual spindle gyroscopes or three-axis gyroscope certainly; Be used to detect the angular speed of two faces or three faces, just its volume, weight etc. can become complicated a little.
Behind the angular speed when said gyroscope 100 is sensed portable terminal and brandished, can the data of relevant angular speed be sent to baseband chip 200, the baseband chip 200 among the present invention is mainly used in according to this angular speed to come the brightness of backlight 300 is controlled.Specifically, said baseband chip 200 obtains said angular speed from gyroscope 100 after, obtain the brightness value of backlight 300, and control the light that backlight 300 sends corresponding bright according to said angular speed; In said process; Need the brightness value of first backlight 300 and the corresponding relation of angular speed; Specifically can be through a backlight 300 brightness values and angular speed relationship storage module are set in baseband chip 200; The corresponding relation of storage angular speed and brightness of backlight value in this module after obtaining angular speed, obtains the brightness value of the corresponding backlight 300 of this angular speed through this corresponding relation.
For the brightness value of backlight 300 and the corresponding relation of angular speed, multiple mode can be arranged.For example; Can be that the absolute value
of angular speed
is during greater than an angular speed threshold values
; The absolute value relation in direct ratio of brightness of backlight value
and angular speed
then; It is fast more to reach the speed of brandishing portable terminal; Then backlight is bright more; Its concrete computing formula is following:
; Wherein,
is the brightness value of backlight;
back of the body is the brightness maximum of backlight; Ω is an angular speed;
is the angular speed threshold values;
angular speed maximum,
is the angular speed absolute value.
As shown in Figure 5, it is the corresponding relation sketch map of angular speed and brightness of backlight, and in angular speed threshold values scope, the brightness value of backlight is zero, and during greater than the angular speed threshold values, the brightness value of backlight and angular speed increase with the relation of direct ratio.
Also being provided with a scheduled time in the baseband chip 200 in the present invention is provided with module; Be used to be provided with a scheduled time; Every separated said scheduled time is obtained angular speed from gyroscope, make baseband chip 200 need not to obtain in real time angular speed, just obtains from gyroscope 100 at regular intervals; Reduce the processing complexity of baseband chip 200, raise the efficiency.
Baseband chip 200 among the present invention also is used to control the light that backlight 300 sends corresponding bright, and this baseband chip 200 is to control the light that backlight 300 sends corresponding bright according to the brightness value of the corresponding backlight 300 of angular speed.
After said backlight 300 receives the luminous instruction of baseband chip 200, send the light of corresponding bright according to the brightness value of said backlight; Backlight 300 among the present invention has comprised KBD-LIGHT and/or screen backlight lamp.
Based on said method, the present invention also provides a kind of brightness control method of the portable terminal with the glo-stick function, and is as shown in Figure 6, comprises step:
Angular speed when S101, gyroscope induction portable terminal is brandished, and said angular speed is sent to baseband chip;
S102, baseband chip obtain said angular speed from gyroscope, obtain the brightness value of backlight according to said angular speed, and control the light that backlight sends corresponding bright;
S103, backlight receive the luminous instruction of baseband chip, send the light of corresponding bright according to said brightness value.
Further, said step S102 specifically comprises: the brightness value that obtains the corresponding backlight of said angular speed according to said angular speed and brightness of backlight and the corresponding relation of angular speed.
Further, said step S102 specifically comprises: baseband chip whenever obtains said angular speed at a distance from a scheduled time from gyroscope.About the principle of said method, the existing detailed description in the method in front is so repeat no more.
The portable terminal and the brightness control method thereof of band glo-stick function of the present invention, the angular speed of brandishing portable terminal according to the user is controlled the brightness of backlight, and the speed that the user brandishes is fast more; Then brightness of backlight is high more, thereby reaches the dazzling effect of glo-stick, even and owing to the brightness of backlight can be controlled by the user; Thereby reached the purpose of saving electric weight, the present invention uses simple and convenient, with respect to the glo-stick of traditional chemical substance manufacturing; Have characteristics such as fluorescent lifetime length, environmental protection; And from the application and development angle of mobile phone, the present invention is simple, and software development is very simple.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, concerning those of ordinary skills, can improve or conversion that all these improvement and conversion all should belong to the protection range of accompanying claims of the present invention according to above-mentioned explanation.
