Abstract

A display screen comprises a receiving module, a control module electronically connected to the receiving module, a backlight drive module, and a backlight module. The receiving module is configured for receiving incoming calls and transmitting the incoming calls to the control module. The control module is configured for converting incoming calls to control signals and transmitting the control signals to the backlight drive module. The backlight module has different operation modes according to the incoming calls. One end of the backlight drive module is electronically connected to the control module, the other end of the backlight drive module is electronically connected to the backlight module. The backlight drive module is configured for driving the backlight module. A method of shining the display screen is also provided.

Claims

1. A display screen comprising:

a receiving module receiving wireless signals of incoming calls and converting the wireless signals of incoming calls to electronic signals;

a control module storing contact information, ringtones, and links of ringtones to contacts, the control module determining whether a telephone number included in the electronic signals has a link to the stored contact information and a corresponding ringtone, the control module generating backlight control signals corresponding to the determining result; and

a backlight drive module receiving the backlight control signals and driving a backlight module to dynamically flash according to the backlight control signals;

wherein the backlight drive module includes a digital to analog conversion unit and a backlight drive module circuit, the digital to analog conversion unit converts the backlight control signals into analog signals and then transmits the analog signals to the backlight drive module circuit to drive the backlight module.

2. The display screen as claimed in claim 1, wherein before transmitting the incoming calls to the control module, the receiving module processes the incoming calls.

3. The display screen as claimed in claim 1, wherein the control module includes a memory unit, a process unit, and a converting unit, the memory unit is used to store telephone numbers, the process unit is used to determine whether the received telephone number is stored in the memory unit and whether the received telephone number has a corresponding ring tone stored in the memory unit, if the received telephone number stored in the memory unit or the received telephone number does not have a corresponding ring tone in the memory unit, the process unit processes a default ring tone and transmits the default ring tone to the converting unit;

if the received telephone number record is stored in the memory unit and the received telephone number has a corresponding ring tone stored in the memory unit, the process unit processes the corresponding ring tone and transmits the corresponding ring tone to the converting unit, the converting unit converts sound signals of the corresponding ring tone to control signals used to control the backlight module and transmits the control signals to the backlight drive module.

4. The display screen as claimed in claim 1, wherein the backlight drive module circuit is a current source circuit.

5. The display screen as claimed in claim 1, wherein the backlight module includes “

n”

light emitted diodes, thus having 2ⁿ operation modes.

6. The display screen as claimed in claim 5, wherein notes of a ring tone corresponding to an incoming call correspond to the operation modes of the backlight modules.

7. A method of shining the display screen, comprising:

providing a receiving module;

receiving an incoming call with a telephone number using the receiving module;

providing a control module;

transmitting the telephone number to the control module, the control module comprising a memory unit, a process unit, and a converting unit;

providing a backlight drive module circuit and a backlight module;

determining whether the received telephone number is stored in the memory unit and whether the received telephone number has a corresponding incoming ring tone stored in the memory unit using the process unit;

wherein if the received telephone number is not stored in the memory unit or the received telephone number does not have corresponding incoming ring tone stored in the memory unit, the process unit uses a default ring tone and transmits the default ring tone to the converting unit;

if the received telephone number is stored in the memory unit and the received telephone number has corresponding incoming ring tone stored in the memory unit, the process unit runs the corresponding incoming ring tone and transmits the incoming ring tone to the converting unit;

converting sound signals of the incoming ring tone or the default ring tone to control signals and transmits the control signals to the backlight drive module using the converting unit;

driving the backlight module using the backlight drive module.

8. The display screen as claimed in claim 7, wherein the backlight module includes “

n”

light emitted diodes, thus having 2ⁿ operation modes.

9. The display screen as claimed in claim 8, wherein notes of an incoming call correspond to the operation modes of the backlight modules.
