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.

Example Embodiment

[0022] See figure 2 , Which is a schematic diagram of a flat panel display disclosed in an embodiment of the present invention. Such as figure 2 As shown, the flat panel display 100 includes an input unit 110, an adjustment unit 120, and an output unit 130. 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 refer to Figure 3 to Figure 4 ,among them image 3 Shown is a flowchart of a method for adjusting the display signal value of a flat display device disclosed in an embodiment of the present invention, and Figure 4 Shown as image 3 The signal value change schematic diagram of the display signal value adjustment method shown. Hereinafter, the display signal value adjustment method of the present invention will be introduced by taking the display signal value of one pixel as an example. Such as Figure 3 to Figure 4 As shown, the display signal value adjustment method of this embodiment includes step 210: receiving a display signal value, wherein the received display signal value is between a maximum display signal value of 255 and a minimum display signal value of 0; step 220: adjusting the received display The signal value is used to generate an adjusted display signal value, where the maximum display signal value is kept unchanged during adjustment, and the remaining display signal values ​​are reduced; and step 230: output the adjusted display signal value.
[0024] Specifically, when the adjustment unit 120 receives the display signal value from the input unit 110, the adjustment unit 120 reduces the received display signal value according to a linear adjustment method to generate an adjusted display signal value. Preferably, the linear adjustment method described above can adjust the received display signal value according to the following formula:
[0025] Output=Input-Offset×(255-Input)/255
[0026] Among them, Output is the adjustment result obtained by performing linear adjustment, Input is the received display signal value, and Offset may preferably be an adjustment amount set by the user (8 in this embodiment), or a preset display Signal value. After obtaining the above adjustment result Output, it must be confirmed that the adjustment result is a reasonable value. Generally speaking, the display signal value will fall between 0 and 255. Therefore, when the aforementioned adjustment result Output is less than 0, the adjustment unit 120 will output 0 as the aforementioned adjusted display signal value; otherwise, if the aforementioned adjustment If the result Output is not less than 0, the adjustment unit 120 can directly output the adjustment result Output as the aforementioned adjusted display signal value.
[0027] In other words, in the above linear adjustment method, when the received display signal value is the maximum display signal value of 255, the maximum display signal value 255 is maintained as the adjusted display signal value, and the received display signal value is closer to the maximum display signal value. 255, the adjusted display signal value is less reduced compared with the received display signal value; and when the received display signal value is closer to the preset display signal value 8, the adjusted display signal value and the received display signal value Compared with the value, the degree of reduction is greater, and the degree of reduction is closer to the preset display signal value 8.
[0028] To sum up, the flat-panel display device and the method for adjusting the display signal value of the present invention can not only enhance the dark-state display effect of the flat-panel display device, but also can keep its maximum display signal value unchanged during adjustment, that is, keep it. The brightness is unchanged, so the contrast of the picture displayed by the flat display device can be enhanced while maintaining the bright display effect of the flat display device as much as possible.
[0029] Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding All changes and deformations shall belong to the protection scope of the appended claims of the present invention.
