In the work unit selection step 41G, the working diode unit is selected from the organic light-emitting diode unit of each pixel 11(s), and at the same time, a plurality of spare diode units are obtained, wherein the spare diode unit is Each pixel is opaque to the organic light-emitting diode unit. In the failed pixel inspection step 42A, the organic light-emitting device 3GG is configured to include a failed pixel and provide a failed pixel. The result is a failed pixel inspection silkie, and the defective pixel inspection step is step 42G. If the failed pixel check result is YES, then the failed unit _ ν step 430 is performed. In the failed unit inspection step, the system checks that the failure image contains at least a failed diode unit and provides a failed order::: result, wherein the failed diode unit is a spare diode unit. =°44Λ, the alternative unit selection step is performed in the alternative unit to select the alternative pole=set: the system, the failed unit check result Du Shu彳mi# the replacement unit selection step 440 second control: the device 302 is in the address table In the middle, the body is marked 70 as a failed diode unit. The singularity indicates that the second embodiment of the present invention is not the case, and the second step is not intended. If the failed unit check node is replaced by step 4; if the failed order 200849189 element check result is yes, then a second substitute unit selection step 440b is performed. In the first replacement unit selection step 440a, one of the spare diode units is selected as the replacement diode unit.

If the working diode unit of the pixel 116 fails, the failed diode unit will draw more current than normal operation. Therefore, if the current device tears the current drawn by the pixel column 5〇4a, In normal maintenance, the control device can determine that the pixel column 5G4a contains the failed satellite diode unit through the measured value, and the control device 3Ό2 determines the pixel column 5〇4a as the failed pixel column. When the control device 506 determines the pixel column 504a as the failed pixel column, the control device 5〇6 selects the replacement diode for all the materials UG of the column 5〇4a. In addition, the working diode of each pixel 110 The unit's diode unit positions are the same. Referring to Fig. 9, there is shown a flow chart showing the control method of the organic light-emitting device 500 according to the third embodiment of the present invention. In the working step 7, the working _ pole unit and the spare diode unit of each pixel 110 are selected, wherein the pixel (four) polar body is the organic luminescence contained therein. The two-pole unit is the one of the remaining diodes, and the spare diode of the pixel 110 is the spare diode 2, which is the remaining organic light-emitting diode unit. When the pixel 110 displays its pre-port and color, the H 110 ❸ working diode unit emits light having a preset color, so that the pixel 110 displays its preset color. In the failed pixel column check step 620, the current pre-measurement device 502 is used to check whether the organic light-emitting device=)0 contains the failed pixel column 5〇4, and provides a failed pixel column check result, wherein the failed pixel column refers to A column of pixels containing a failed working diode. If the failed pixel column check result is no, the failed pixel column check step 62 is continued. If the failed pixel column check result is yes, then the failed unit check step 630 is performed. In the failed unit check step, the system checks whether the pixel UG of the failed pixel column contains the failed two poles one morning and provides the failed unit check result. In the alternative unit selection step 640 + ' select the replacement diode single & The working diode of pixel 110 operates in a single operation, wherein the binary reading of the alternate diode unit of each pixel 110 is the same. In addition, when the replacement unit selection step 640 ends, the = device 506 is tied to the address table, and the failed working diode unit is labeled as a failed diode unit. a 4, 10, which is a flow chart showing a step of selecting a unit according to a third embodiment of the present invention. If the lapsed person has a magnetic fruit: 杳社贝1入仃第—the replacement unit selects step 640a; if the failed unit check :: the second is yes, then the second alternative unit selection step 嶋 is performed. In the first selection, among the six, the replacement diode unit is selected from each pixel 110 of the failed pixel column. In the second alternative step 16 200849189 element selection step 640b, the replacement diode unit is selected from the spare diode unit of each pixel 11〇 of the failed pixel column, but the diode unit of the replacement diode unit is replaced. The position is different from the position of the diode unit of the failed diode unit and the failed diode unit. In the following description, the control method 600 will be described more specifically by way of an example. Referring to FIG. 9 again, in this example, the working unit selection step 61 selects the organic light emitting diode unit 118 as the working diode unit of the pixel 116; and selects the organic light emitting unit 128 to do The working diode unit is a pixel I% C; the organic light emitting diode unit 518 is selected as the working diode unit of the pixel 516. Next, a failed pixel column check step 620 is performed. If the failed pixel column check step 620 finds that the pixel column 604a has failed, then the expired early element check step 630 is performed. If the failed pixel column check step 620 determines that each pixel column 504 is functioning properly, then the failed pixel column check step 620 is continued. In the failed unit check step 630, the address table is used to check whether the organic light emitting diode units 120, 122, 124, 130, 132, 134, 518, 520, 522, and 524 have failed. If the failed cell check step 43 determines that the pixel column 504a does not include the failed diode cell, then the first replacement cell selection step 640a is performed to select one of the organic light emitting diode cells 120, 122, and 124. An alternative diode unit of the pixel 116; one of the organic light-emitting diode units 13A, 132, and 134 is selected as the replacement diode unit of the pixel 126; and the organic light-emitting diode unit 520, One of 522 and 524 is selected as the replacement diode unit of pixel 516. If the organic light emitting diode unit 124 of the pixel 116 is detected to have failed, one of the organic light emitting diode units 120 and 124 is selected as the replacement diode unit of the pixel 116; from the organic light emitting light 17 200849189 One of the polar body units 130 and 134 is selected as the replacement diode unit of the pixel 126; and one of the organic light emitting diode units 520 and 524 is selected as the replacement diode unit of the pixel 126. The number of current detecting devices of the third embodiment of the present invention is less than that of the second embodiment, so that cost-saving effects can be achieved. Alternatively, the control methods 400 and 6 can be accomplished in other ways, such as by visual inspection by a user and manually selecting an alternate diode unit. Although it is less convenient for the user to personally control the money control method and _, the cost of the control device and the current detecting device can be saved. While the present invention has been disclosed by the embodiments of the present invention, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application attached. [Simple description of the map]
