Classification: CPC G | IPC G

Claim 6:
7. A display module, comprising:
a data driving circuit, comprising:
a selecting unit comprising a selector, a first receiver, and a second receiver; and
a signal conversion unit,

a scan driving circuit;
a Liquid-Crystal-Display (LCD) panel; and
a display control circuit,
wherein the selecting unit is configured to receive an image signal in a digital form, and is configured to, based on a control signal, transmit the image signal to either the first receiver or the second receiver,
wherein the first receiver and the second receiver are connected with the selector in parallel,
wherein a first resistor is disposed between a non-inverting input end of the first receiver and an inverting input end of the first receiver,
wherein a second resistor is disposed between a non-inverting input end of the second receiver and an inverting input end of the second receiver,
wherein an image signal sequence outputted by the first receiver and an image signal sequence outputted by the second receiver are mutually inverted,
wherein the second receiver inverts the image signal and then transmits the image signal inverted to the signal conversion unit,
wherein the control signal represents a display mode of a pixel unit for image display, the signal conversion unit is configured to convert the image signal into a grayscale voltage in an analog form, and the grayscale voltage is used to drive the pixel unit to perform image display,
and wherein the display control circuit is configured to receive an original data signal from an external signal source, and output a source output control signal and a gate output control signal individually, and the LCD panel is controlled to perform image display by the data driving circuit according to the source output control signal and the scan driving circuit according to the gate output control signal.
