A method for configuring row drivers in an electronic display comprising a row driver system having - a main row driver column having a plurality of row drivers configured to be in an active state and - a spare row driver column having a plurality of row drivers configured to be in an inactive state, wherein each row driver comprises o a configuration logic adapted to effect an active state or an inactive state in response to configuration data; o a token latching means adapted to receive and to pass a token; and ∘ a latch means adapted to latch configuration data in response to the token being latched by the token latching means; the method comprising: - determining at a CPU/GPU that a row driver in the main row driver column is faulty; - receiving a token, to identify the faulty row driver, - switching the faulty row driver in the main row driver column to an inactive state, and - switching a corresponding row driver in the spare row driver column from an inactive to an active state; whereby the switching of the faulty row driver comprises: - latching from the configuration data at the faulty row driver, which configuration data is configured to effect a change in a state of the configuration logic of the faulty row driver from an active state to an inactive state when the faulty row driver also receives a token with an identifier for the faulty row driver; whereby the switching of the spare row driver comprises: - latching from the configuration data at the corresponding row driver, which configuration data is configured to effect a change in a state of the configuration logic of the corresponding row driver from an inactive state to an active state when the corresponding row driver also receives a token with an identifier for the corresponding row driver; and wherein - each row driver is configured to pass the token to further row drivers within the main row driver column and the spare row driver column. - a main row driver column having a plurality of row drivers configured to be in an active state and - a spare row driver column having a plurality of row drivers configured to be in an inactive state, o a configuration logic adapted to effect an active state or an inactive state in response to configuration data; o a token latching means adapted to receive and to pass a token; and ∘ a latch means adapted to latch configuration data in response to the token being latched by the token latching means; - determining at a CPU/GPU that a row driver in the main row driver column is faulty; - receiving a token, to identify the faulty row driver, - switching the faulty row driver in the main row driver column to an inactive state, and - switching a corresponding row driver in the spare row driver column from an inactive to an active state; - latching from the configuration data at the faulty row driver, which configuration data is configured to effect a change in a state of the configuration logic of the faulty row driver from an active state to an inactive state when the faulty row driver also receives a token with an identifier for the faulty row driver; - latching from the configuration data at the corresponding row driver, which configuration data is configured to effect a change in a state of the configuration logic of the corresponding row driver from an inactive state to an active state when the corresponding row driver also receives a token with an identifier for the corresponding row driver; - each row driver is configured to pass the token to further row drivers within the main row driver column and the spare row driver column.
