Description
本發明關於一種用於顯示面板之時序參數掃描方法。The present invention relates to a timing parameter scanning method for a display panel.
由於目前顯示面板的種類眾多，且不同廠商製造的面板特性並不相同，所以當欲安裝或更換一個新的顯示面板時，需重新編寫針對該型顯示面板的時序參數並編排新的料號，如此會耗費相當多的時間，且無法提高使用不同種類或型號的顯示面板之間的相容性。Due to the variety of display panels and the different panel characteristics of different manufacturers, when you want to install or replace a new display panel, you need to rewrite the timing parameters for the display panel and arrange a new item number. This can take a considerable amount of time and does not improve the compatibility between display panels of different types or models.
本發明提供一種用於顯示面板之時序參數掃描方法，其能提高顯示面板使用時的相容性並簡化不同顯示面板間的替換過程。The invention provides a timing parameter scanning method for a display panel, which can improve the compatibility of the display panel during use and simplify the replacement process between different display panels.

First, a plurality of mutually different timing parameter groups are stored in a data access unit, and the timing parameter groups respectively correspond to different display panels. Then, pressing one of the function keys of the display panel to feed the plurality of test screens respectively defined by the timing parameter groups into a display panel to be adjusted, and displaying the test screens on the display panel to be adjusted At one time, the timing parameter group corresponding to the normally displayed display screen is set as a normal display timing parameter group of the display panel to be adjusted.
基於上述各個實施例之設計，因為對應各種不同的顯示面板的複數個時序參數組已先儲存於一資料存取單元，當欲安裝或更換一個新的顯示面板時，可從內建的這些時序參數組中，掃描出一個可搭配目前使用的面板且正常顯示的時序 參數組即可，不需再重新編寫程式，如此可大幅節省時間並提高顯示面板使用時的相容性，且當有新種類或型號的顯示面板上市時，可擴充該資料存取單元內建的參數組即可涵蓋任何新產生的參數組。Based on the design of each of the above embodiments, since a plurality of timing parameter groups corresponding to different display panels have been previously stored in a data access unit, these timings can be built in from when a new display panel is to be installed or replaced. In the parameter group, a timing is displayed that can be matched with the currently used panel and displayed normally. The parameter group can be used without rewriting the program, which can save time and improve the compatibility of the display panel. When a new type or model of display panel is released, the data access unit can be expanded. The parameter set can cover any newly generated parameter set.

圖2為依本發明一實施例之流程圖，用以說明一種用於顯示面板之時序參數掃描方法的步驟。依本實施例之設計，首先使複數個彼此相異的時序參數組儲存於一資料存取單元，該些時序參數組可各自對應不同種類或型號的顯示面板(步驟S20)，且該資料存取單元例如可為一快閃唯讀記憶體(flash read-only memory,flash ROM)。接著，使由該些時序參數組所分別定義之複數個測試畫面輪流饋入一待調整之顯示面板(步驟S30)，該測試畫面例如可包含圖像、文字或色彩等等，若待調整之顯示面板上正常顯示該些測試畫面之其一時則使對應被正常顯示之該測試畫面之時序參數組設為該待調整之顯示面板的正常顯示時序參數組(步驟S50)，亦即該時序參數組即為驅動該種類或該型號的顯示面板所需的時序參數組。若該測試畫面於該顯示面板未正常顯示，則回到步驟S30選取由該些時序參數組中的另一個時序參數組所定義的另一個測試畫面，並重複上述步驟直到找出驅動該種類或該型號的顯示面板所需的時序參數組為止。2 is a flow chart of a method for scanning a timing parameter of a display panel according to an embodiment of the invention. According to the design of the embodiment, a plurality of mutually different timing parameter groups are first stored in a data access unit, and the timing parameter groups can respectively correspond to different types or models of display panels (step S20), and the data is stored. The fetch unit can be, for example, a flash read-only memory (flash ROM). Then, the plurality of test screens respectively defined by the timing parameter groups are alternately fed into a display panel to be adjusted (step S30), and the test screen may include, for example, an image, a text or a color, etc., if the image is to be adjusted. When one of the test screens is normally displayed on the display panel, the timing parameter group corresponding to the normally displayed display screen is set as the normal display timing parameter group of the display panel to be adjusted (step S50), that is, the timing parameter. A group is the set of timing parameters required to drive a display panel of that type or model. If the test screen is not normally displayed on the display panel, return to step S30 to select another test screen defined by another timing parameter group of the timing parameter groups, and repeat the above steps until it is found to drive the category or This model of the display panel is required for the timing parameter group.
圖3為依本發明另一實施例之流程圖，用以說明一種用於顯示面板之時序參數掃描方法的步驟。依本實施例之設計，測試畫面饋入步驟係由持續按壓一功能鍵所啟動。如圖 3所示，使複數個彼此相異的時序參數組儲存於一資料存取單元後(步驟S110)，可持續按壓一功能鍵以使複數個測試畫面輪流饋入一待調整之顯示面板(步驟S120)，該些測試畫面係分別由該些時序參數組所定義，且該功能鍵例如可為一電源開關。於持續按壓該功能鍵時，可掃描不同的時序參數組並輪流測試各個時序參數組所定義的測試畫面是否可正常顯示，當該待調整之顯示面板正常顯示該些測試畫面之其一時，可再按一次功能鍵使對應被正常顯示之該測試畫面之該時序參數組設為該待調整之顯示面板的正常顯示時序參數組(步驟S140)。若該功能鍵為一電源開關，則此一步驟(步驟S140)可同時關機。3 is a flow chart of a method for scanning a timing parameter of a display panel according to another embodiment of the present invention. According to the design of the embodiment, the test picture feeding step is initiated by continuously pressing a function key. As shown As shown in FIG. 3, after storing a plurality of mutually different timing parameter groups in a data access unit (step S110), a function key can be continuously pressed to feed a plurality of test pictures in turn to a display panel to be adjusted (steps). S120), the test pictures are respectively defined by the timing parameter groups, and the function keys may be, for example, a power switch. When the function key is continuously pressed, different timing parameter groups can be scanned and the test pictures defined by each timing parameter group can be tested for normal display. When the display panel to be adjusted normally displays one of the test pictures, Pressing the function key again causes the timing parameter group corresponding to the normally displayed display screen to be the normal display timing parameter group of the display panel to be adjusted (step S140). If the function key is a power switch, this step (step S140) can be turned off at the same time.
基於上述各個實施例之設計，因為對應各種不同種類或型號的顯示面板的複數個時序參數組已先儲存於一資料存取單元，當欲安裝或更換一個新的顯示面板時，可從內建的這些時序參數組中，掃描出一個可搭配目前使用的面板且正常顯示的時序參數組即可，不需再重新編寫程式，如此可大幅節省時間並提高顯示面板使用時的相容性，且當有新種類或型號的顯示面板上市時，可擴充該資料存取單元內建的參數組即可涵蓋任何新產生的參數組。Based on the design of each of the above embodiments, since a plurality of timing parameter groups corresponding to various types or models of display panels have been first stored in a data access unit, when a new display panel is to be installed or replaced, it can be built in from the built-in In these timing parameter groups, a timing parameter group that can be matched with the currently used panel and displayed normally can be scanned without rewriting the program, which can save time and improve the compatibility of the display panel. When a new type or model of display panel is available, the parameter set built into the data access unit can be expanded to cover any newly generated parameter sets.
