The invention provides a lead frame used for an outdoor displayer, belongs to the technical field of semiconductor packaging, and solves the problems that existing lead frames are high in production cost. The lead frame used for the outdoor displayer comprises a support. The support is provided with multiple support units which are equidistant and are connected. Each support unit comprises a first connecting pin and a second connecting pin which are arranged in parallel. A connecting frame is arranged between the first connecting pin and the second connecting pin. The front end of the first connecting pin upwardly extends so that a first connection part is formed. The front end of the second connecting pin upwardly extends so that a second connection part is formed. The top end of the second connection part is provided with an installing slot. Passages are formed between the first connection part and the second connection part. The lead frame used for the outdoor displayer has advantages of long service life and low production cost.
