Embodiment Construction
[0042] The present invention provides a sub-pixel circuit, an active electroluminescence display and a driving method thereof. PWM driving is applied to an AM (Active Matrix / active matrix) panel structure, which can effectively reduce the driving load and split the sub-pixel Multiple signal lines, thereby greatly improving the resolution.
[0043] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0044] see image 3 , Figure 4 with Figure 5 , the sub-pixel circuit provided by the present invention includes at least one electroluminescence device and a first drive transistor Q1 or a second drive transistor Q2 and a third drive transistor Q3 co...
