Description

BACK LIGHT LED ALLOCATE METHOD OF PORTABLE PHONE}

The present invention relates to a mobile phone, and more particularly, to a method of arranging a backlight LED of a mobile phone to diversify the arrangement and color of a keypad backlight LED.

In general, an LED phone is arranged around the keypad for the keypad backlight, and the LED is arranged in various shapes according to the type of the mobile phone.

In the backlight device used in the mobile phone, a chip LED is used as the light source for miniaturization, and a technology development for uniformly irradiating the light generated from the light source onto the light guide plate is being made.

Until recently, the backlight device has been used as a function for reading information displayed on the screen of a mobile phone display device (LCD) in a dark place, but recently, the light guide plate has been viewed due to various requirements such as design, low power consumption, and thinning of a mobile phone. It is formed thinly, and is capable of expressing various colors, as well as developing technologies to reduce power consumption by using less chip LEDs.

The backlight LEDs are variously arranged in the shape of a mobile phone, and most of the LEDs are not easy to attract attention from consumers due to the simple arrangement of the LEDs, and the color of the LEDs is uniform in green or red according to each mobile phone.

The present invention has been made to solve the above problems, and relates to a method of arranging a backlight LED of a mobile phone to improve the preference by arranging the LED around the mobile phone keypad by varying the design and color according to the needs of the consumer. .

1 is a schematic view showing a state in which the backlight LED arrangement method of the present invention mobile phone is applied.

FIG. 2 is a schematic view showing the arrangement of a backlight LED on a key PCB in FIG. 1; FIG.

Figure 3 is a schematic diagram showing a variety of colors of the backlight LED in Figure 1;

Figure 4 is a schematic diagram showing a variety of arrangement of the color of the backlight LED on the key PCB in Figure 3;

FIG. 5 is a schematic view showing a variety of lightings of a backlight LED in FIG. 1; FIG.

FIG. 6 is a circuit diagram showing an LED port individually controlled in FIG. 5; FIG.

The present invention for achieving the above object, in a dark place, the mobile phone is equipped with a backlight LED for viewing the keypad, the plurality of backlight LEDs, on the key PCB, in a variety of designs to suit the needs of the purchase generation It is characterized by arranging.

The plurality of backlight LEDs are implemented in various colors to increase the visual effect.

The plurality of backlight LEDs, in order to increase the visual effect, characterized in that the lighting at a time interval set by the user.

Hereinafter, with reference to the accompanying drawings, the operation and effects of the backlight LED arrangement method of a mobile phone according to the present invention will be described in detail.

1 is a schematic view showing a device to which the method of arranging the backlight LED of the present invention is applied. In the related art, a plurality of backlight LEDs for viewing the keypad of the mobile phone in a dark place are arranged in a uniform shape of a triangle or a quadrangle. A plurality of backlight LEDs are arranged in various designs to suit the purchasers' generation, that is, the LEDs are placed on the key PCB as shown in FIG. 2 at desired positions between the keypads as desired designs.

For example, in the case of a mobile phone having a purchase generation of lovers, the purchase preference of the lovers can be improved by arranging a plurality of backlight LEDs on the key PCB in the shape of a heart.

In addition, the color of the plurality of backlight LEDs may be implemented in various colors as shown in FIG. 3 rather than in one conventional color, thereby satisfying various needs of consumers.

That is, as shown in FIG. 4, a colorful color scheme is designed by arranging a plurality of backlight LEDs arranged at appropriate positions on the key PCB as LEDs having a desired color.

And, as shown in Figure 5, by differentiating the lighting time of the plurality of backlight LEDs at predetermined time intervals, the plurality of backlight LEDs are variously flickered, that is, as shown in Figure 6 to individually assign a port to each backlight LED and hardware or The software enables the desired backlight LED to blink in various forms by activating it at the desired time.

In other words, the present invention improves consumer preference by arranging a plurality of backlights arranged around the keypad of the mobile phone in various designs to meet the needs of consumers and by varying the color and lighting time of the backlight LED.

The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

As described in detail above, the present invention has an effect of improving consumer preference by arranging LEDs around a mobile phone keypad in a variety of designs and colors according to consumer needs.

Claims (3)
