Through sub-district 1, it is assumed that light path set 1 includes 52 light paths, is designated as light path 1-light path 52 respectively.
Configuration device determines that the light path quantity (52) in sub-light path set 1 more than max-thresholds (50), then configures device and obtains
Take the redundancy of each light path in sub-light path set, it is assumed that the redundancy of light path 1-light path 52 is successively decreased successively.
Configuration device deletes light path 1, and judges the son that whether there is light path quantity in 100 Ge Zi districts of touch screen less than 45
District, it is assumed that after deleting light path 1, the light path quantity in 100 Zhong Gezi districts of Ge Zi district of touch screen is all higher than 45, it is determined that light path 1
State be state to be deleted.
In sub-light path set 1, the light path quantity in addition to the light path (light path 1) of state to be deleted is 51, more than max-thresholds
(50), then configuration device continues to obtain the state of light path 2, concrete: configuration device deletes light path 2, and judges the 100 of touch screen
Whether Ge Zi district exists the light path quantity sub-district less than 45, it is assumed that after deleting light path 2,100 Ge Zi districts of touch screen deposit
In the light path quantity sub-district less than 45, then recover light path 2, and determine that the state of light path 2 is reserved state.
In sub-light path set 1, the light path quantity in addition to the light path (light path 1) of state to be deleted is 51, more than max-thresholds
(50), then configuration device continues to obtain the state of light path 3, concrete: configuration device deletes light path 3, and judges the 100 of touch screen
