Abstract
The invention discloses a method for applying an EL (electro luminescent) cold light source in a mobile phone in a cold light technology, which is realized by the following steps: a, processing the EL cold light source to obtain a thin paster with a specific shape and adhering the thin paster to the shell of the mobile phone or printing the thin plaster on the shell of the mobile phone by a printing technology; b, connecting the EL cold light source with a chip by a wire, wherein the chip is arranged in the mobile phone and can convert low-voltage direct current into high-voltage alternating current; c, connecting the chip to a power supply of the mobile phone so as to provide a direct current power supply; and d, connecting the chip with a control circuit, wherein the control circuit controls the actions of the chip by an interface. In the method, the printing technology is utilized to realize the randomness, various luminous patterns and various luminous colors which can not be realized by other technologies.
Description
Technical field
The present invention relates to the construction design method of mobile phone, specifically is that a kind of EL cold light source (is called for short: the brilliant light source of magnesium) in the application method of mobile phone.
Background technology
At present, the application of mobile phone has reached degree very widely, is machine of staff basically, and some businessperson has two ones, we can say on be very general necessity for life.Mobile phone in the past is portable phone, and name is as its machine, and build is heavy.Through constantly research and development, the technology of mobile phone is constantly brought forth new ideas, and it is integrated more and more higher, the more and more littler function of mobile phone also from strength to strength, but the outward appearance of mobile phone and light do not obtain everybody attention.If the outward appearance of mobile phone adds the light source that a beautiful sporty motion picture again can be energy-conservation and will the people like not let go.Luminescence technology scheme of the prior art is difficult to satisfy the random purpose of design.
Summary of the invention
At the problems referred to above, the present invention aims to provide and a kind of EL cold light source in the cold light technical matters is used method to the mobile phones design.
For realizing this technical purpose, the solution of the present invention is: a kind of EL cold light source (in the application method of mobile phone, is characterized in that realizing by following steps: a, the EL cold light source is processed into the thin paster of given shape, is attached at or is printed in the phone housing position; B, above-mentioned EL cold light source are connected to the chip that low-voltage direct can be converted to high-voltage alternating that is arranged at mobile phone inside by lead; C, chip are connected to cellular phone power supplies, provide DC power supply by it; D, chip also are connected with a control circuit, and this control circuit is by the action of interface control chip.
Control circuit in the steps d can be set on the mobile phone base band chip.
The scope of adjusting frequency of described chip is 400HZ～800HZ.
The printing technology of can using this programme realizes the inaccessiable randomness of other luminescence technologies, luminous pattern variation, the variation of luminous color.Luminous pattern variation shows as can print various patterns, such as cartoon, personage's scenery with hills and waters, sign, the Logo of company or the like.The variation of luminous color shows as uses different luminescent powders just can send different light colors.The combination of random pattern and light color just can strengthen the effect of handset shell outward appearance innervation greatly.
Description of drawings
Fig. 1 is the circuit structure diagram of chip of the present invention.
Embodiment
Principle of the present invention is: (be called for short: the brilliant light source of magnesium) to realize opening the EL cold light source luminous for chip for driving, and it is (luminous perhaps to close the EL cold light source by interface control EL cold light source for the software that moves on the controller of mobile phone; Fortune uses the same method also can control luminous intensity of EL cold light source and the luminous quantity of control EL cold light source.Its mainly be a kind of can be luminous, rich color, very thin about 0.03 millimeter, the athermic light emitting source of flexible cold-light through after the developmental research repeatedly by a chip that can be modeled to the DC direct voltage AC alternating voltage and frequency is adjusted to 400HZ～800HZ, drive the lamp sheet through change of program after lighting, thereby after reaching multicoloured variation effect, be installed on the mobile phone.
Mobile phone involved in the present invention comprises mobile phone body, cellular phone power supplies, phone housing and EL cold light source, and its concrete application method is:
A, the EL cold light source is processed into the thin paster of given shape, is attached at the phone housing position;
The lead of b, above-mentioned thin paster is connected to the chip that low-voltage direct can be converted to high-voltage alternating that is arranged at mobile phone inside;
C, chip are connected to cellular phone power supplies, provide DC power supply by it;
D, chip also are connected with a control circuit, and this control circuit is by the action of interface control chip.
Control circuit can be set on the mobile phone base band chip.The scope of adjusting frequency of described chip is 400HZ～800HZ.
The EL cold light source needs high pressure and AC signal to drive.As shown in Figure 1.For chip of the present invention is the chip that low-voltage direct is converted to high-voltage alternating, its operating principle is to utilize certain switching frequency with inductance (coil) low-voltage direct to be boosted into high-voltage signal, utilizes the discharge skill to convert direct current to approximate AC signal again and reaches.Need external diode, the main function of diode is a store charge.The luminous degree of EL cold light source is relevant with voltage and driving frequency, within the relevant inductance of the selection of inductance (coil) with switching frequency resistance littler, the brightness height of will healing, but power consumption stream also increases thereupon.
The above; it only is preferred embodiment of the present invention; not in order to restriction the present invention, every foundation technical spirit of the present invention to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection range of technical solution of the present invention.
