本發明係關於OLED顯示器，尤指一種可對OLED面板因不同局部溫度所造成的畫面亮度不均勻現象進行補償的OLED面板驅動方法。The invention relates to an OLED display, in particular to an OLED panel driving method capable of compensating the non-uniform brightness of the picture caused by different local temperatures of the OLED panel.

OLED(organic light-emitting diode；有機發光二極體)顯示器已廣泛應用在現今的各種電子產品中。於操作時，各像素之有機發光二極體之導通電流係由對應的顯示資料決定。然而，當一有機發光二極體(organic light-emitting diode, OLED)的溫度改變時，即使驅動電壓相同，通過該有機發光二極體的電流量卻會與溫度成正相關，致使該OLED面板之畫面產生亮度不均勻的問題。OLED (organic light-emitting diode; organic light-emitting diode) displays have been widely used in various electronic products today. During operation, the conduction current of the OLED of each pixel is determined by the corresponding display data. However, when the temperature of an organic light-emitting diode (OLED) changes, even if the driving voltage is the same, the amount of current passing through the organic light-emitting diode will be positively correlated with the temperature, causing the OLED panel to There is a problem of uneven brightness on the screen.

依上述的說明可知本發明揭示了一種OLED面板驅動方法。請參考圖4，其繪示本發明之OLED面板驅動方之一實施例的流程圖。如圖4所示，該方法包括以下步驟：在一OLED面板中設置一溫度感測器陣列(步驟a)；依該溫度感測器陣列感測到之一溫度陣列對一幀顯示資料進行一補償運算以產生一幀輸出顯示資料(步驟b)；以及依該幀輸出顯示資料驅動該OLED面板(步驟c)。According to the above description, it can be seen that the present invention discloses a method for driving an OLED panel. Please refer to FIG. 4 , which shows a flow chart of an embodiment of the OLED panel driver of the present invention. As shown in Figure 4, the method comprises the following steps: arranging a temperature sensor array in an OLED panel (step a); performing a frame display data according to a temperature array sensed by the temperature sensor array Compensation operation to generate a frame of output display data (step b); and drive the OLED panel according to the frame of output display data (step c).

請參考圖5至圖8，其中，圖5繪示當圖3中的顯示層210的各個顯示區塊對應不同溫度時的示意圖；圖6繪示圖5的顯示層210中各個顯示區塊之不均勻發光亮度的示意圖；圖7繪示本發明所產生之一對應補償係數陣列的示意圖；以及圖8繪示圖6中之顯示層210中各個顯示區塊之不均勻發光亮度經圖7的補償係數陣列加權處理後呈現均勻發光亮度的示意圖。Please refer to FIG. 5 to FIG. 8, wherein FIG. 5 shows a schematic diagram when each display block of the display layer 210 in FIG. 3 corresponds to a different temperature; FIG. A schematic diagram of uneven luminous brightness; FIG. 7 shows a schematic diagram of a corresponding compensation coefficient array produced by the present invention; and FIG. 8 shows the uneven luminous brightness of each display block in the display layer 210 in FIG. Schematic diagram showing uniform luminance after weighting by compensation coefficient array.

具體而言，在本實施例中，顯示層210包括九個顯示區塊212，該些顯示區塊212的數量對應於該些溫度感測器110的數量。透過這樣的配置，OLED顯示器12即可透過該些溫度感測器110對應偵測該些顯示區塊212的溫度。Specifically, in this embodiment, the display layer 210 includes nine display blocks 212 , and the number of the display blocks 212 corresponds to the number of the temperature sensors 110 . With such a configuration, the OLED display 12 can correspondingly detect the temperatures of the display blocks 212 through the temperature sensors 110 .

如圖5所示，各該顯示區塊212可能有不同的分佈，例如自九宮格左下角的該顯示區塊212沿著對角線方向朝右上移動時，各該顯示區塊212分別具有第一溫度T1、第二溫度T2、第三溫度T3、第四溫度T4及第五溫度T5，且以第一溫度T1 ＜ 第二溫度T2 ＜ 第三溫度T3 ＜ 第四溫度 T4 ＜ 第五溫度T5為例。由於通過有機發光二極體的電流量與溫度彼此正相關，因此，當該控制電路驅使顯示層210發光時，第五溫度T5的顯示區塊212在未經校正的情況下會具有較高的亮度，其情形如圖6所示。As shown in Figure 5, each of the display blocks 212 may have different distributions. For example, when the display block 212 in the lower left corner of the Jiugongge moves upward and rightward along the diagonal direction, each of the display blocks 212 has a first temperature T1, second temperature T2, third temperature T3, fourth temperature T4, and fifth temperature T5, and the first temperature T1<second temperature T2<third temperature T3<fourth temperature T4<fifth temperature T5 is example. Since the amount of current passing through the organic light-emitting diode is positively correlated with the temperature, when the control circuit drives the display layer 210 to emit light, the display block 212 at the fifth temperature T5 will have a higher Brightness, the situation is shown in Figure 6.

此時，該些溫度感測器110在測得該些顯示區塊212的溫度值後將該些溫度值傳遞至該控制電路。之後，該控制電路會依據該些溫度值對一幀顯示資料進行上述的補償運算以產生一幀輸出顯示資料，以對顯示層210發出的光進行補償校正。如圖7所示，該控制電路可產生一補償係數陣列，其包含多個補償係數310，以分別對該些顯示區塊212的顯示資料進行加權運算，其中，補償係數為小於或等於1的正數。At this time, the temperature sensors 110 transmit the temperature values to the control circuit after measuring the temperature values of the display blocks 212 . Afterwards, the control circuit performs the above-mentioned compensation calculation on a frame of display data according to the temperature values to generate a frame of output display data, so as to compensate and correct the light emitted by the display layer 210 . As shown in FIG. 7 , the control circuit can generate a compensation coefficient array, which includes a plurality of compensation coefficients 310 to perform weighting operations on the display data of the display blocks 212 respectively, wherein the compensation coefficients are less than or equal to 1 A positive number.

更進一步而言，若將圖5中第一溫度T1的該顯示區塊212對應的亮度定義為1單位，則該第二溫度T2、該第三溫度T3、該第四溫度T4及該第五溫度T5的各該顯示區塊212對應的亮度例如是1.25單位、1.5單位、1.75單位以及2單位，此時可將對應最左下該顯示區塊212的補償係數310設為最大值1，並將其餘八個補償係數310分別設定為上述單位倍率的倒數，即(W1,W2,W3,W4,W5) = (1.00, 0.8, 0.67, 0.57, 0.5)；或者可透過一預設的查找表，其記錄溫度與補償係數的對應關係，來產生該些顯示區塊212的補償係數310。如此一來，在各該顯示區塊212的顯示資料經過對應的各該補償係數310的處理後，該顯示層210的輸出光的亮度將均勻地校正為1單位，從而提高使用者的視覺感受。Furthermore, if the luminance corresponding to the display area 212 of the first temperature T1 in FIG. 5 is defined as 1 unit, then the second temperature T2, the third temperature T3, the fourth temperature T4 and the fifth temperature The brightness corresponding to each display block 212 of temperature T5 is, for example, 1.25 units, 1.5 units, 1.75 units, and 2 units. At this time, the compensation coefficient 310 corresponding to the lower left display block 212 can be set to a maximum value of 1, and set The remaining eight compensation coefficients 310 are respectively set as the reciprocal of the above-mentioned unit magnification, namely (W1, W2, W3, W4, W5) = (1.00, 0.8, 0.67, 0.57, 0.5); or through a preset look-up table, It records the corresponding relationship between the temperature and the compensation coefficient to generate the compensation coefficient 310 of the display blocks 212 . In this way, after the display data of each of the display blocks 212 are processed by the corresponding compensation coefficients 310, the brightness of the output light of the display layer 210 will be uniformly corrected to 1 unit, thereby improving the user's visual experience .

另外，如前所述，在進行該補償運算時，本發明亦可先利用一記憶體預存與多個不同溫度對應之多個伽瑪對照表，然後將該溫度陣列中之各元素的溫度值各指向所述多個伽瑪對照表中之一對應之伽瑪對照表，並依該些對應之伽瑪對照表將該幀顯示資料轉換成該幀輸出顯示資料，從而使OLED面板具有一均勻的顯示亮度。In addition, as mentioned above, when performing the compensation calculation, the present invention can also use a memory to pre-store a plurality of gamma comparison tables corresponding to a plurality of different temperatures, and then use the temperature value of each element in the temperature array each point to a corresponding gamma comparison table among the plurality of gamma comparison tables, and convert the frame display data into the frame output display data according to the corresponding gamma comparison tables, so that the OLED panel has a uniform display brightness.

依上述的說明可知，本發明可提供以下的功效：According to the above description, the present invention can provide the following effects:

1.本發明的OLED面板驅動方法可藉由一溫度感測器陣列量測一OLED面板的複數個顯示區塊的溫度值，並依該些溫度值對該些顯示區塊的顯示資料進行一數值調整運算，從而提升該OLED面板之畫面顯示品質。1.
