Embodiment Construction

[0026] In conjunction with the accompanying drawings and specific embodiments, the present invention is described in detail as follows.

[0027] Fig. 1 is a circuit diagram of the present invention for controlling two groups of LEDs to emit light. As shown in the figure, LED1101, LED2102, LED3103, and LED4104 are a group of light-emitting diodes that emit light in digital mode; LEDa105, LEDb106, LEDc107, and LEDd108 are a group of light-emitting diodes that emit light in letter stroke mode. Each group of LEDs is connected in parallel with each other. The positive pole of LED1-4 is connected to the DC power supply, the negative pole is connected to the collector terminal of transistor Q1A109, the emitter terminal of transistor Q1A109 is grounded, the base terminal of Q1A109 is connected to the DBB (Data BaseBand, digital baseband) 111 GPI (general purpose interface, general purpose interface device) is connected to O1, the positive pole of LEDa-d is connected to the DC power su...

Abstract

The present invention proposes a mobile terminal exhibiting different keyboard symbols in different input modes, wherein, a set of LBDs are arranged in a position near to the number symbols; another set of LBDs are arranged in a position near to the non-number symbols; when the input mode is a number one, the set of LBDs near to the number symbols irradiate and the set of LBDs near to the non-number symbols extinguish; and when the input mode is a non-number one, the set of LBDs near to the non-number symbols irradiate and the set of LBDs near to the number symbols extinguish.

Description

technical field [0001] The invention belongs to the field of mobile communication terminals, and particularly relates to a mobile terminal keyboard using two sets of LEDs (Light Emitting Diodes) to highlight different keyboard symbols. Background technique [0002] In previous designs, the numeric characters and alphabetic stroke characters on the mobile terminal were always printed together and in different orientations. The LEDs under the keyboard of the mobile terminal for illuminating characters are all lit together, and when the user changes the input mode, the LEDs will not change when they are lit or extinguished. [0003] And once the position of the LED under the keyboard is determined, the brightness of the characters near the LED will always be brighter. For users, they hope that under different input modes, the brightness of the characters they want to see can be increased, so that they can be visually highlighted and easy to operate. This puts forward new requi...
