Problems solved by technology

[0005] However, the known method for adjusting the display signal value also needs to subtract the preset display signal value of 8 when the display signal value is the maximum display signal value of 255. Therefore, the known method for adjusting the display signal value not only enhances the flat panel display. The dark state display effect, but also weakens the bright state display effect of the flat-panel display at the same time, making the picture displayed by the flat-panel display darker overall

Embodiment Construction

[0022] see figure 2 , which is a schematic diagram of a flat panel display disclosed by an embodiment of the present invention. like figure 2 As shown, the flat panel display 100 includes an input unit 110 , an adjustment unit 120 and an output unit 130 . Wherein, the input unit 110 is used to receive the display signal value, and the adjustment unit 120 is electrically coupled to the input unit 110 to receive the display signal value received by the input unit 110 and adjust it to generate an adjusted display signal value, and output The unit 130 is electrically coupled to the adjustment unit 120 to receive and output the adjusted display signal value. The specific method for the adjustment unit 120 to adjust the display signal value received by the input unit 110 to generate the adjusted display signal value is as follows.

[0023] Please also refer to Figure 3 to Figure 4 ,in image 3 It is a flow chart of a display signal value adjustment method of a flat-panel dis...

Abstract

The invention relates to a method for adjusting a display signal value of a flat panel display device. The method comprises the following steps of: receiving the display signal value, wherein the display signal value is between the maximum display signal value and the minimum display signal value; adjusting the display signal value so as to generate an adjusted output signal value, wherein the maximum display signal value is kept invariable during adjustment and the other display signal values are reduced; and outputting the adjusted display signal value. The invention discloses a flat panel display device simultaneously.

Description

technical field [0001] The present invention relates to the field of black compensation in display technology, and in particular to a method for adjusting the display signal value of a flat-panel display device using black compensation and a flat-panel display device using the method. Background technique [0002] With the development of technology, flat panel display devices (such as liquid crystal display devices) are widely used in mobile phones, notebook computers, desktop display devices and In various consumer electronic products such as televisions, it has gradually replaced the traditional cathode ray tube display device and has become the mainstream of the display device. [0003] A flat-panel display device generally includes a plurality of pixels. When the flat-panel display device is working, each pixel of the flat-panel display device displays the received display signal value to display a corresponding picture on the flat-panel display device. In order to adju...
