Description of the invention: 'Technical field to which the invention pertains>> The present invention relates to a display device and a display panel. [Prior Art] Organic light-emitting diode (OLED) components have the advantages of self-luminous, high brightness, high contrast, light weight, low power consumption and fast response, and have been gradually applied to various displays. Imaging systems, such as organic light-emitting diode display devices. The organic light-emitting diode elements can be classified into a passive matrix (active matrix) and an active matrix (Active Matrix) according to the driving method thereof. However, the passive matrix type is limited by the driving mode, and has shortcomings such as short life and large area, so the active matrix type can be applied to high-performance and large-sized display applications. The active matrix organic light emitting display can be driven using an amorphous silicon (A-Si) thin film transistor (TFT) or a low temperature polycrystalline silicon (LTPS) thin film transistor. The advantage of using an amorphous germanium thin film transistor is that the initial characteristics of the manufactured thin film transistor are relatively similar, and the above-mentioned characteristics are, for example, the threshold voltage (VTH) of the element. However, the disadvantage is that the critical voltage of each component drifts with time and the degree of drift of each component is different, thereby causing vertical undulation (mura) phenomenon on the display surface. The advantage of using a low-temperature polycrystalline germanium film transistor process is that since the grain of the polycrystalline dream is larger than the grain of each of the amorphous crystals, the defect can be reduced. 201025243 • High carrier mobility is obtained, The transistor is made smaller and then increases the aperture ratio of the alum. In addition, due to the improved carrier mobility, some of the panel peripheral driving circuits can be simultaneously fabricated on the glass substrate along with the thin film transistor process, thereby greatly reducing the number of wires, thereby greatly improving the characteristics and reliability of the organic light emitting panel, thereby making the panel manufacturing. The cost is greatly reduced. However, due to the manufacturing problems of the low-temperature polycrystalline germanium film transistor, the initial characteristics of the thin film transistor may be slightly different, which may cause the longitudinal corrugation of the surface. In order to solve the problem of longitudinal corrugation, the prior art proposes a method of data voltage compensation, which stores the threshold voltage of each element when displaying each gray scale, and compensates the input of each element by the threshold voltage of each element. The data, in turn, allows each element to display the correct color. However, this method has the disadvantage of requiring a relatively large memory space to store a large amount of data, and additionally requires an additional component to process the memory space, resulting in an increase in production cost. The prior art proposes another way of circuit compensation, which is to set up a compensation unit in the pixel, and compensate the input of the element data of each element by the compensation unit, so that each element displays the correct color. However, since the compensation unit usually utilizes a combination of complex transistors, the aperture ratio of the halogen is lowered. Therefore, how to provide a display device and a display panel capable of not increasing the production cost and not reducing the opening ratio is one of the current important issues. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a display device and a display panel which do not increase the cost of production 201025243 and which do not reduce the aperture ratio. • To achieve the above object, the present invention provides a display panel comprising a plurality of pixels and a multiplex circuit. Each element is electrically connected to a data line, and has a display control switch and an organic light emitting unit. The multiplexed circuit is electrically connected to the bismuth and is disposed in one of the non-display areas of the display panel, and has a multiplex selection unit and a compensation unit. The multiplex selection unit outputs a data signal according to a multiplex signal. The compensation unit is electrically connected to the multiplex selection unit _ and the halogen. The compensation unit outputs a data compensation signal according to the data signal to control the display control switch of each element to turn on the organic light emitting unit. To achieve the above object, the present invention provides a display device comprising a display panel. The display panel has a plurality of pixels and a multiplex circuit. Each element is electrically connected to a data line and has a display control switch and an organic light unit. The multiplexed circuit is electrically connected to the halogen and is disposed in one of the display panels. The multiplex circuit has a multiplex selection unit and a compensation unit. The multiplex selection unit outputs a data signal according to a multiplex signal. The compensation unit is electrically connected to the multiplex selection unit and the halogen. The compensation unit outputs a data compensation signal according to the data signal to control the display control switch of each element to turn on the organic light emitting unit. According to the display device and the display panel of the present invention, the compensation unit compensates the data signal of the input element, so that each element displays a positive color. Among them, the compensation unit and the multiplex selection unit are electrically The connection is made in the non-display area. Compared with the prior art, the compensation unit of the present invention does not affect the aperture ratio of the halogen. In addition, since the present invention is in the circuit mode 201025243, the data signal of the input element is compensated. Compared with the conventional method of voltage compensation, the display device and the display panel of the present invention do not need to add additional components, that is, the production cost is not increased.
